from an objective point you're absolutely right, but for me it's always pure fun. I don't notice how time went by if i do such things. And i know there are a lot high fidelity examples on Youtube (and hopefully soon on DTube) which are a way more professional. I'm self-taught in that area and i think everybody could learn that if he wants. Recently i had a great conversation with a drawing artist here and she confirmed that's a lot of time and hard work needed to get to a determined level of skill, but that doesn't matter if you really want it, my opinion.

Thank You!
