Yupp. Realizm is the best way to start.
besides. the part you said first about being gifted. Suuuuure some people learn fast. But everyone were rookies at some point.
Look at me for instance. My drawings still suck (acording to me anyways).
Mostly cause i haven´t practised very much lately. But that's how it is with everything. Practise,Practise,Practise. ^_^ Just hang in there. Do your best. And go with the style you find suits you the most in the end. belive me, it's the best to do.
Though if you like. You can drop me a line on msn and i can give you a few pointers and send you a few pages with basic, "yet extremely important" art consepts.
I'm looking forward to see your art in the future.
