Don't get discouraged! Here's one of my horse drawings from 2009, and below it is now. Persevere, Paint, and you'll make progress in heaps and piles. (: All of the artists here are very polite and more than willing to help out, too. Feel free to contact me if you ever need anything! :3
I remember this, too. I drew it in the waiting room while I was pregnant with my son.
And this is Creampuff, taken from the tutorial I'm working on.
Study and reference is going to be your best friend, believe me. (: As boring as it sounds, study works. I watched videos, took pictures, drew and drew more, and watched slow-motion videos. It won't be perfect on day 1 or 3, but it can take a matter of months if you work hard enough. You're already making improvement that I can see and I applaud you!
