I illustrate about 8 to 12 hours a day. After awhile I feel as though I'm working in a void. I've come to the conclusion I need to sketch(digital) from reference at least 10-30 minutes a day. I'll put them on my sight to keep me on top of it. I'll upload them to scraps at the end of the week.
Between the sketchbook in my coat pocket and dry erase pen in the shower, I believe I can put in an extra 2 hours a day.
My day job with Marvel Comics tends to be darker(Ghost Rider). The cartoons balance out the images of blood, mayhem, skulls and and demons. Though it might make it seem even worse in comparison.
I remember you had come to visit and talk for our art club at Keithley when I was in 8th grade and it took me until now to remember your name I'm so glad I was able to find your deviantart, I'm really diggin' the art.
