So today I did what I said I was going to, and painted a picture on 8 x 11 watercolour paper. It went okay, and I was pretty happy with the end result. I can't just paint because it is still pretty unfamiliar to me, so I draw it first and then paint. I couldn't get the shadows quite right, but for the first full drawing not on a 3.5 x 2.5 inch atc card I think it came out okay. I used an old art cover exchange cover I had by ACE 160, Gene Berryhill to get an idea for what to draw and paint. Anyways, here is the end result:
I still have a lot to learn about watercolours, but I'm hooked.
