While searching for the photo of my painting Not Even Death Shall Part Us for the previous post, I ran across a bunch of other stuff.
Okay, I know they're not fine art, but at the time (I was 20 or so) I was very happy with how they turned out; now doubly-so because I know I didn't lay anything out first. I just grabbed a pen and started drawing.
Artistic ability may indeed be a gift, but I know this much: if you don't use it, it deteriorates over time. Take this from a guy who really hasn't produced any art in over ten years and is now almost terrified at the thought of drawing anything.
