Well I suggest to put more detail into the grass(if you weren't gonna do that already) where the steam meets with it but not to much cause then it will make the pic look too busy. I like where you're going with the shading and if you do need some photos it really does help to find what clothes looke like when they fold.I'm glad you added the feet it adds so much more to the drawing. The two guys on the right they're looking alittle tense maybe lower their shoulders alittle to loosen them up. Oh yeah and if you do the grass dont forget to put little shades here and there. I know that's a mistake I forget to do all the time.
LOL, people are my bigest problem. Just wait till its colored I'm worried that the back and foreground will out shine the subjects because I have always loved doing nature scenes better than humanoids
Yeah I can have that problem where one thing was supposed to stand out but another that isn't all that important stands out the most. It bugs me like you wouldn't believe!
