Don't say that, of course I didn't learned all that stuff in one sitting. Before I had my character illustration class, more or less I already have practiced drawing such things many times in the past... way past.
For people who has "no talent" they only rely on practice and yes, I strongly believe that I am one of them.
Man, having talent doesn't mean that you're drawing everything beautyfull. Having talent means that you're learning faster and discover new tricks earlier that most people. IMO all people can draw beautyfull but some of them just need to practice little more to get same effect.
