shiNIN- lovely anime faces! Good character going on in your work.
Bellhop-- nice quick studies and good to see values in there too. Well done.
AdrianNagorski-- Very dynamic! Hard to say if there is any cc, some of the faces look odd, but then I've seen rugby player pics before and their faces DO look odd.
kayness- yey blue pencil. Beautiful birds, nice values going on. For the negative space stuff, do you set up a skeleton first? I ask because a lot of your pics don't have that much negative space (like a triangle between an arm and a hip), and that can make it really tricky.
darkops-- nice thubnails! Some really great stuff in there. Wow, tones of figures too! Well done!
