Well I may not be an artist but if you were picky about your backgrounds I'd look at little/classic sonic's hand other than the reaching for the chili dog attempt that makes this picture look so cute (btw!) :3 <3 he also could have his hand on a mountain for balance :/ So maybe finishing the mountain above or below his hand? What do you think?
So lovely and sweet! Classic Sonic on top of Modern Sonic's head and tries to reach for the chili dog while Modern Sonic looks the other way! I really love their expressions in this! So magnificent! Your pictures are so clean, tidy and very overwhelming!
