I have been attending part time since Spring of last year and it has been great. If anything I have been wondering if I should quit my job and just go for it full time. Classes are online so I will get the bad out first...technology always has its hang ups but the occasional problems there are pretty much the problems everywhere. I have so far taken painting with Jason Manley and Jon Foster, Head/portrait painting with Vanessa Lemen and Ron Lemen, and Composition and Color I and II with Marshal Vandruff. So this has pretty much been an all star line up. The work is demanding but so far I have repeatedly asked myself the same question, "why didn't I get this the first time in art school?". The instructors just really know their craft and are more than willing to show you not just technique and theory and THOUGHT process.
A typical class might involve lecture, demonstration, critique, or any and all of the above and they are all very valuable. Classmates are also quite awesome and if you hit a wall they are there to help you over it.
Hope that helps and good luck!
