Just trying to improve, slowly but sure. I've decided to do this exercise. I painted the face of an asian girl out of my imagination.
I knew I wanted her to have big lips and extremely prominent cheek bones, other than that I had nothin else in mind and went with whatever came to mind.
Next, I found photo reference and did a study of an Asian girl under similar lighting conditions. I used Grace Park because I'm a Battlestar Galactica nut.
Finally I did a third face, trying to apply what I learned from the study as much as possible. I think I learned a lot and I'm hoping the third face shows improvement from the first. I think this is a great exercise to directly apply what you learn from a study, and to help retain it by forcing yourself to see the flaws in your imaginative work and correct them.
I really recommend trying this out! I'll be doing a LOT more of these
ALSO. io9 posted about my JLA stuff, which is overwhelming me with geekout-ness. There seem to be a lot of opinions about my stuff on there, for better or worse, but a lot of people have actually made some really good points about the flaws in my designs! Anyway here's the article:
