Hello ! I'ma lock this thread because ponycreator images are in a weird area of precomposed art by General Zoi. However, you're totally free to post pony creator images in a status or blog entry, or use them as references in other sections! ♥

As for learning to draw, we do have a Resources subsection for visual art you could ask around in~ It's a good place to look for help or feedback on a piece, and you might find some people there willing to point you in the right direction. Or, there's a similar section for OCs if you're just worried about design and plotting them out and such.
If you're completely new to drawing and wanting to start, I'd also suggest looking around online for a handful of tutorials on basic drawing technique, and pointers on how to draw the subject (ponies I assume?) you're most interested in. Basically, the more information you can dig up and look through (even if some of it doesn't seem useful at the time), the better off you'll be. Just as well, the more you draw and attempt to apply what you learn, the quicker you'll improve.
Anyways, have a great day!
