this is just a thumbnail, i want to redraw it again as a Cover for this comic ^^
soooo
i had this idea 3-4 days ago...
long story short...
Those two are really good friends in a place where food, water and any kind of vegetation is really rare....the boy (the guy on the right side) is somekind of a mechanic and he searches for plane wrecks and other kind of wrecks that he can scrapping,plundering and stuff. He sells it at a Junkyard. The little one on the left side is a Girl from a species wich are wandering often. (and yes they supposed to be small even if they are really old) she lost her Family after a ambush from local bandits and she gets lost.... so the boy found her in a abandoned building almost starved to death. He helped her and she decided to follow him...now they walk together to a unsure future...

I dont have names for them yet...but i'm searching :P
