You have passion. That counts for a lot I can promise you that...in the beginning I can give you the best piece of advice someone ever gave me...dedicate an hour a day drawing. TO JUST drawing. Try to routine that and like youll go far from there but commit to that one hour a day for drawing. It's okay if its spread out throughout the week but the biggest thing with art is passion. Someone who is hungrier of an artist than you will come up behind you and take your spot before you even realized it. The other tip I can give you when you draw...focus on basics first. Technique, construction, light and shadow that sort of stuff. ALSO focus on proportion more than anatomy. Anatomy has a lot to do with a lot of shapes that become very very complicated with things move and contract/etc. What I can tell you from my own experiences is to just draw...be passionate about it. Maybe you'll go pro where I could not. But as long as you pursue the passion itself you will improve much faster. Everything I learned I learned in an internship I landed and through some of my HS classes. You have to do the rest with the same lessons that artists learn with you now? One more thing, on my art gallery I have the same art tutorials I was given in my own internship. Use those charts/etc. You will learn. But as I said earlier, you have passion and desire you will go far.
