Nice job Keith. I bought my Wacom tablet for exactly that purpose. Your first effort is bang on. In using Old Crow's advice and wise words, "PRACTICE, PRACTICE AND PRACTICE."
I found using the mouse to be quite tedious and probably cut down the computer time by 50% using my tablet. Let's face it, we all would prefer more time on our saws.
Here's my latest portrait attempt that was completed on the weekend. It's strange how different people have different perceptions as I didn't originally like my attempt and asked on here for help. Mahendra came up with what I believed to be a much superior version but when showing it to my customer, they preferred my version. Go figure, to each their own.
