Reporting for duty?
-Sea creatures in general
-The Portugese man-of-war
-Baroque and Rococo
-Art Nouveau (NOT Art Deco!)
-Space ships with weird moving parts or tranformations for no apparent reason.
-When half of something cilindrical is mirrored so the lighting doesn't make any sense
-Pop culture references
-Regardless of any like/dislikes you may or may not be using in your gift, I prefer a display of skill or "original" ideas/designs (whatever that means anymore) to appeals to emotion or other vagueness that modern art tends to try.
-If you feel like doing a mockup, but have difficulty coming up with anything: I've been somewhat obsessed with Mega Man lately,although I wouldn't want you to just do something Mega Man. I feel that would be too easy. You're free to make any other type of mockup too though.
I hope that's not too much or overly complicated. Sorry if it is.
