Sent back for quality control purposes. Feel free to start a WIP thread for feedback and critique, then resubmitting when revised. The placement of the important elements in the image is problematic. When two objects touch, it creates visual tension. Your speech bubble, character, and Earth are all stack on top of one another. My advice would be to move the planet to the side and raise the speech bubble a pixel or two. The planet is surrounded by banding, which doesn’t function the same as aa. The character’s main green should be lighter so he’s more readable. The character himself is rather stiff and boring, a more interesting pose or angle would help.
Maybe when that supposed asteroid hit the earth killing all the dinosaurs, the ones on the outer edge of the impact got knocked into space.
Thanks for the feddback- I'll see what I can do :)
