Future Da Vinci

[Elk]

a recent drawing in A4 i made when i was bored at school with a
2b pencil and hb sometimes, as usuall...
its not finished and i want you to help me to find a good background for it,
i cant think of anything that would suit it ;_; some say that i should draw
the tower of pisa or the eifeltower...but i dont think they would look good on it...
also, i used no reference for this pic i just wanted to draw a face and then
i made an old man with those those tubes...it turned out like that
and i thought he resembles da vinci a bit so i named it "Future Da Vinci",
because of the tubes that is...and now i need a background that has
something futuristic but yet something renaissance-like, the scan lacks
alot of detail because the light of the scanner took it all away (thats why
i hate scanning pencil drawings), im gonna buy a new scanner next...
sidenote: im sorry for the ugly lips, i suck at them
but im open for any critique or suggestions
