Hm, this is an insane project to have done >_< I'm glad I didn't have art teachers that harsh lol. The checkered pattern looks fine to me, it can be hard to do vanishing points sometimes, especially when they are checkered like that O.o. Luckily you have the 3 targets in the middle, which automatically drive your eye toward them, so the eye doesn't wander elsewheres lol. And the organic shapes you have upon the wall, remind me of metallic cookie cutters . Lol, excellent job for one who finished at 3 in the morning XD.
You know what...during the critique at my school many people said the organic shapes reminded them of either cookie cutters or gingerbread men too! They also said the 3 targets looked like 3 saw blades comming at them, ha ha. Thank you BamboozledByAnime!
