I got about 2 months of free time and drew every day from morning till night. It was a hard work, but it was worth it. By mistakes we learn. I began with watching at the objects in my room and trying to understand how light is going.
Wow! That's very Dedicated work indeed! Definitely worth all that hard work. Trial And Error is the best way to learn anything. Hmm, I have noticed I've thought the same with things like how light bends and effects things i see daily, but have never figured out how to apply any of it to art. Light(ing) is a pretty difficult puzzle until solved, then its more or less "Oh yeah! why didn't i try that the first time?"
