I'd say definitely redraw the orc, the pose is way too unbalanced.
Back on the goblin though, my problem is it comes off as more of a knight thanks to the head bit looking like one of those visored helmets more than a goblin face. On top of that, it took me until just now to even recognize they weren't wearing armor! I think maybe saturating the green some more and reducing how shiny those pectorals are might help to abate that!
