1. Travels: I missed two classes because of my trip to Chicago, and when I go to Alaska I would miss four more. That's at least one critique, possibly two. It was going to have a negative impact on my grade - don't want that!
2. Heat: It's been freakin' hot this week, and this affects the paint. I would squeeze some acrylic paint out of the tube, mix some water in, and start painting...only to have the paint dry out long before I finished. I know that I can buy retarders to slow this drying process, and I may do that for my own practice. But I'm a slow painter, and if it's frustrating me this much when I'm only working on a small 9" x 12" painting I know it's really gonna bother me when I move on to a larger canvas.
I'll have to make sure to paint on my own, just to keep the skills going, but I won't be doing it in an official class.
