An awesome incentive for artful improvement, and what a work of art to kick it off! Very nicely drawn, and entirely symmetric too. I suppose for art like this you draw half and then mirror it? Or maybe there's a filter/program to automatically mirror even while you draw? It looks beastly.
As for ideas... how about a fuzzy cloud-covered blue and green sphere of planet Earth, and the neck/head of a giraffe popping through this blanket of fuzz, reaching into interstellar space to gaze at stars and maybe some funky alien vessel passing by? My first thought was a pixel-perfect scene out of the classic Doom games, a collage of blood and gore with all the monsters of the game reaching out with gleaming fangs and hands, spitting fireballs and plasma, the main character cowering in fear under this overpowering force of evil, the grand Cyberdemon a menacing siolhouette towering behind all other monsters.... but maybe that'd be too much? Would be incredibly awesome to see, though. Looking forward to what great creative work this project might procure!
