Various styles
 

At some point I want to reopen a shop. As it's been a long time, the prices I sold for are a bit outdated at this point I think. I don't know how well I've been judging my own art's worth, so I decided to ask.

What do you think various styles of mine are actually worth?
Chibi: ex1, ex2, ex3
Ipad: sketch, finished
Pencil: ex1, ex2, ex3
Colored Pencil: ex1, ex2, ex3

Most of my examples are old because I haven't done much worth uploading to the interwebs in years, but what I have drawn does look better from my college years.
