Welcome to Biorust, JRG.
I doubt that you can find a better site, if you are looking for "evoluting" your artwork etc. Well, I haven't...
Many of the users here posess a great deal of knowledge, just ask if you need help, and you will probably get the help quite fast.
And sorry about milkdrop, he can be cind of harsh sometimes. Don't be scared.
Good luck, but don't remember to have fun on the way there!
