Making John Willie proud.
The drawing itself is just correct. There's a couple of details that makes the work lose a bit of flair, like the lady head, it's either too broad or the eyes seem lost in the middle of it. And maybe the drawing is a bit small, cause the line is quite thick and the small details suffer because of it. The nipples look really bad because of this... And the bird almost can't be seen, too small ans lost among other white spaces that draw the attention out of it. Though looking a bit dirty, the shading is really good and makes an excellent work of conveying fabrics and textures, and the proportions of the body are fairly good-looking.
As I told before, as an illustration, it still lacks punch...
... But as a fashion sketch, it works all right.
What I really want to highlight about this picture is that the design of the suit is absolutely terrific. It's a gorgeous BDSM dress that I can't help to adore. The leather and rings makes it very fetishistic, while the feathers and the shoulder lace add a lot of beauty to the design. Expose the nipples and crotch to bring out the sexy nature of it, and complete it all with the birdcage helmet... Excellent presentation idea bringing a bird in the model's hands.
Man, be careful. Some designer could totally steal this. Stay aware.
