Could you tell us more about those color studies? What's the procedure? And what specifically do you learn about color by doing them? I need to work on color so I'm interested in color exercises.

Your figures and background seem to be in two different perspectives. Look how the far edge of that grill nearly lines up with those distant trees — that’s one big grill! Compositionally, it’s a good idea to overlap your foreground elements. Bring that grill down so the reclining guy’s head is a bit in front of it — that’ll help us feel the depth. You might be able to overlap the duck and table with Deadpool’s leg. That sort of thing. Cuz right now the figures are all kind of floating and don’t feel related. Beyond that, it’d be good to establish basic values earlier on in your process, with thumbnails. Most of the time what makes a composition work or not work is the abstract arrangement of values.
