I don't normally leave comments, but since this is your first one you said, and since you have asked for critique, I have a few things to say...

The general concept is nice, and this image has a LOT of potential and I think you framed her well. But there are a few things that I personally would have done differently.

First, the colors... Now I know a lot of other artists would disagree with me on this point, but personally I don't like images that are lacking in color unless they are black and white or sepia. I'm also not a fan of sepia unless an "aged" look is what you are deliberately going for. I don't feel that an "aged" look suits this particular model very well, or at least not this picture of her, so I think sepia is out. Black and whites in my opinion need to have really good contrast and clear imagery to be appealing to me unless they are deliberately abstract, which this image is not. So with all of that in mind, I think this image could use some more color. Now if it were me, I would probably have gone with a black and white style background, with perhaps a very slight, very subtle hint of blue, then make the geometrical structures that you used to frame her with more of a gold metal color and texture (a little more yellow, and a bit brighter, though not much, and maybe a little more nebulous in color shifts). Then for the foreground image of her, I would have gone with something more natural looking and bright, so she stands out better against the rest of the backdrop.

Second, a word on texture... The background image... that sort of glassy-distortion blended blob, looks absolutely great in my opinion, and since female form is frequently very contoured with few hard lines and hard angles, it is also fitting for a background of an image of a woman (so are very straight-lined backgrounds of singular direction for shape contrast, but I dislike most angular geometrics for such backgrounds). The framing structures on the other hand are too hard-lined-angular for my tastes, and I feel they don't blend as well with the either the background or the foreground as they could have if they were slightly rounded off, particularly in the corners. I think that if you were to blend off the lines between the main structure and it's shadow structure underneath, and also between the main structure and it's highlight segments above, and then you were to round off the corners a bit where the angles meet (not a lot, just slightly), particularly if such blending was inconsistent rather than uniform, I believe it would blend a lot better and would leave the viewer with their eyes drawn more to the woman and less to the frame. Framing should accent and compliment, and draw the eyes TOWARD the main part of the image, they shouldn't detract from it. And in this case I feel that the framing detracts slightly, particularly at the upper-right where the colors contrast so completely that there is more contrats in the framing angle than between the background and the model's face.

A further point on texture... The image of the model (and this is probably more to do with the original photograph that anything you've done with it) seems to me to have two underlying problems. First, the hair texture is almost totally imperceptible and makes her hair look not quite natural. This is probably either to do with the coloration or the lighting, or both. And second, her skin looks a bith rough. It looks to me like there are Digital Photograph Artifacts present there (and such artifacts are often more visible against skin than anything else) and I think it might look better if you could smooth them off a bit (Paint Shop Pro has a useful filter for doing precisely that if you can get hold of a copy, and while I don't recall off hand how to do it in Photoshop, I can just about guarantee there is a way).

Otherwise though, great image, lots of potential... definitely stick with it.

Thanks for advanced comment this is more than i expected well, you are right about framing, it's too visible at first sight. Texture wasn't the best quality so that's why it looks like that. And as for colors, i think it's a matter of taste Anyway thanks again for comment, i'll keep in mind your advices.

I think the color is ok, if we all did things the same it would be boring, I like the image overall and the fact the you put the main subject off centre, only one tip from me - always sign your work - you worked hard on it - you should get the credit, nice job though - looks a hell of a lot better than some of my first efforts.

This is such a beautiful picture. I'm going to be honest, I don't know much about art, textures, colours...I'm lucky if I manage to put on a pair of socks that match in the morning, but I think it's very nicely done. Everyone has their own style, and yours in admirable. *sighs* Wish I had the skill to do something like that.

Thanks and BTW i don't know much about art, textures, colours etc. too. I learned everything myself. Just use your imagination
