Oh wow! 8D These are some fantastic pieces of art! o3o

I wouldn't call myself an expert on pricing, but I'll be happy to help ya out as much I can. xD

The traditional sketch I'd probably be happy paying at least 3+ mill for, as the lines are really, really clean. xD

The chibi I'd pay 4+ mill for, as well as the line art. o3o Once again, nice crisp lines. 

The two bottom colouring examples could definitely sell for 7+ mill each, more for neater colourings. xD  

Once again, I'm no expert. |D So I would use these prices only as a guideline, if at all, as people tend to have their own prices when it comes to art. Nevertheless, I hopes what little information I gave you helps. ^^ 

That's fine. xD I guess now's as good a time as any to think up a human character. |D

Hrm, could you maybe sketch up a lady with an untidy, medium length pony tail? A large-ish zip up hoody, with a T-shirt underneath, baggy pants with pockets, like cargo pants? And...I dunno, skater shoes? As far as personality goes, she's a slacker. xD

I'd love a quick sketch of that character right there, if you'd be so kind. ^^ 

No problem. xD I'm glad what little help I could give you helped a bit. ^_^

Thanks again for the sketch! <3 

I'd pay at least a million for that sketch, so cute and un-sloppy ^.^

For the Chibi, I'd say maybe 3-5 million and probably the same price for the line art.

Then, for the colored ones, probably 5-6+ million. Beautiful art by the way!
