I didn't do any warm up sketches today. But I did do this after dinner tonight. Just to play with color for a while. Digitally painting is great. Experimentation is so easy. You do something you don't like or if you go down a road that is not working out, you just back up. No mess. You still need to know a bit about painting but anyone can jump in and try this. I use a Wacom Tablet for most everything I do on the computer. My daughter just got the Wacom Bamboo and she loves painting in Photoshop and Painter now. It was difficult to use a mouse. Like painting with a brick. Wacom has a beautiful tablet called the Cintiq 20WSX. It is a 20" wide screen tablet you draw on. It cost $1,999.00. One day..."sigh".
This took about 45 minutes from pencil start to Photoshop painted.
