This is my first post on conceptart.org
because I thought this is only for 2d art
but now I see we can post our 3d work too.
So I decide to post my WIP here
the arms in general need alot of work but especially that right arm.Transpose is a great tool but even after using it you should still work back into the model and make any geometry fixes that might be needed.I think you should give this a model a little extra attention and make the needed fixes.
