:) it's OK if you are not satisfied with your drawing...BTW, i am seldom satisfied with mine LOL, but the horse sketch (the whole one) is well captured. In my opinion horses are not easy objects to draw because of they seemingly complicated joints (knuckles) on their legs and proportions. It can be mastered by repeating the same drawing over and over again 10, 20, 30 times if necessary. You did well, so keep on sketching and doodling :)
