I'll begin with stating the obvious. I am HeroHorse and I am looking for some advice on pricing my work. It's not very good but I can draw more than a wiggly line, which is something, I guess. Some constructive criticism is appreciated. Here are some examples of my drawings.

Oh my gosh!  This one is soooooo cute: http://th00.deviantart.net/fs71/PRE/f/2014/148/3/8/picsart_1401314576837_by_herohorse-d7k4du8.jpg

I say depending on the detail work and complexity that they are probably anywhere from the 5 - 15 mill range.  Hope this helps. ☺

Thanks so much! I'll keep that in mind when I'm selling some.
