It may be quite slow, but what's good about this is you are making a progress. I always believe that we are gifted with so many artists. Some of there are just to lazy to discover it on their own. Once you have talent, you need to work hard to hone your craft. Just like what you are doing. You know in yourself that you are still far from being perfect, but at least you are working so hard just to attain perfection or the better you can do, for that I really commend you for trying really hard.
