My god what talent you have, simply amazing!! O.O I just love the eyes and details you put on the hair! The shading is very cool in such harmony with the human anatomy and the clothing folds also very detailed and coherent!! I love it!
Okay, before I start, if you are going to draw based off a photograph, link the photograph back. It's easier to find the original, a good comparison and means credit is given were credit is due and you won't get into trouble. I know if you just google his name, you will get the image, but a lot of people won't, so just make it easier for yourself and them. As with your last image, amazingly done. This time the hair is less rushed looking and messy, it looks like the original photograph which is brilliant. The facial features are brilliant and spot on. The background is neat and all the right size and shape. The shading of the straps to the dress is none existent and as with the last review the shading can be darker in places than it is. A good example on this image to help you is that you cannot tell where the hair ends and the shadows begin. By making the shadows darker, you can tell the difference. Amazing work with you piece.
