I think you did a very good job for the picture you choose, it has potential to become difficult when trying to portray your value and shape pictures, but it looks great.
i think you did i great job on these portraits. My favorite is the first one of shape because you used shapes throughout the whole thing and it looks awesome! the value one is good but i think it has to much lettering as shading, a little to much is going on i would like the see more shading with the letters.
I like what you did in the value portrait with the hand - very cool. I think it's shaded well too.
I like these because i think the original photo was cool to work from. Just finding the right shapes to fit your ring could have been cool to play around with. i like your value portrait but i think your pointer finger gets a little lost.
I think this was a good image to work with. Used some good shading but could do a little more of it perhaps.
these are really good. ummm, can't think of any suggestions.
Good job on your portraits! The only change I would make is that the value portrait is a little confusing with all of the different elements combined. They came out good otherwise.
I think your value one came out the best. I don't think i really like the dollar signs though for the shape one and I got a little lost in that one in general.
good job, I like how the shape one really worked out well for your ring.
