Don't fret, backgrounds give me hassle too, in fact most of the backgrounds are just me scribbling with a wide brush, blurring it all too omit the fact I cant background for anything and then apply some relevant textures to it.
I did put some effort into the background of the third last one, though. It wasn't a 2 minute mashup, more like... 6 minutes. :O
Some of the characters depicted here took several days to draw.
This one was 7, and I think it's the longest I've ever taken over drawing something.
Sometimes I speed draw things so they can't go and take forever.
I definitely wanna do another of these sometime.
