I'm just looking to see how much SP or USD people would be willing to offer for things like the following pieces. Feel free to leave comments or crits as well, but I really just mainly looking for price suggestions.

1 2 3 4 5 Thank you very much to anyone who leaves a suggestion! C: I hope to open a shop once I get a few ideas of what I should ask for!

I'd guess anything in the region of 5 to 6 mill for sP, possibly more for the completely coloured/painted one. The best thing to do is start toward the top end then if you're not getting any interest, drop the prices. That's what I did. If you're getting loads of interest, more then you can keep up with, then raise them.

Also, it's useful to segregate your art into distinct styles with different prices based on how long each style takes as an estimate. A price for line art on it's own, a price for the flat oekaki style, and a price for the more painterly style. That way people know exactly what they're getting which makes everything less confusing. Check the art forums and just basically do what the successful threads are doing. =D
