They're claiming this planet in the name of Mars
EDIT (6/6/20): Shrank the martian on the left and moved things around.
Yeah, I think that just might be it. I'm not too good with compositions yet, so I'll need to experiment some more with it :)
Yeah, I can see why the green you used for AA and midtones could be unappealing. It might alternately be a composition thing? His body is leaning right up against the vertical line, and his arm and foot are right along the horizontal ones. And he's super close to Marvin. IDK, I like the art a lot, it's just weird that the elements don't jell together when they're so nice on their own.
True! I tried using the other greens in the palette and I didn't find them very appealing on them. I'll mess with it some more but that's a pretty valid critique. Thanks for pointing it out!
I kinda wonder whether you shoulda used a darker shade of green on the non-Marvins? The one on the left is a little distractingly bright, and distracts from Marvin as the central focus of the piece
I love this btw.
