The Guitarist by @sakama (Sakkaku Amano)
Probably the best realistic drawing to date. Drawing from photographs is really relaxing because you don't have to think too much and it always turns out better than freeform stuff. The only problem I have with this is the legs. I can't seem to be able to justify which is higher than the other. @_@
His right knee appears to be at least on the same level as the left, but there's not enough above it, which makes his leg look smaller and causes the perspective issue. I think that's the problem with the legs.
In any case, this is a wonderfully drawn picture. The perspective is wonderful (otherwise), I love the shading, and it's just generally very well done. I particularly love the hair. Nice work.
