Honestly I go on-and-off when it comes to sites like this, but while I actually open the site...
How much do you think my art's worth?

Well, I'm new to Mene so I'm not sure what's a good price, but you're very good. Do you use Photoshop? If you were going to go digital full color I'd make it kinda high in whatever would be considered average-moderately high range =]

I use Paint tool SAI. Abused Brush tool to the max :)
OTL It's that or MS Paint.

Thank you, though!

those look pretty good :]
