nah you didn't post it yet. Those leaves look a little shabby if you push the size to full screen. It looks like this is done within 20 mins or even less. I don't know how long it normally takes to create a HD-picture (nobody says high quality picture anymore, everything is high definition now, you are high definition^^)
LOL. Well yes, silly! That is why it is called a color rough/ or comp or study. It is meant to be 'shabby' because what you are interested in is the colors, how they work together so you don't want to spend a lot of time painting. And as a matter of fact it I did only spend 20 minutes on it. that is kind of the point.
