Yeah, it took me a long time to like what I drew too. I find that the more you draw, the better you get. When it's all said and done, you look back on your first drawing and think "Wow, I've improved so much! I can't believe I didn't think I could draw.".
Really, you are good. It just takes some practice and experimenting to find what you like about your drawing style and mold that into a piece of art you absolutely love.
