I am having sort of a problem lately. I work for a small game studio, and I do a lot of pitch work. I notice that my painting style seems to be a problem for some of the pitches that I do. I have no problem drawing in different styles, but I seem to have hit a wall when it comes to my actual painting. I have a very cartoony painting "style" and I really, really want to grow and expand my skill set.
I plan on working really hard to rectify this, and was hoping that some of you might be able to help me. How would you go about learning or adapting a new style? Resources, advice, anything. I really dislike when I feel my art is off and it will gnaw at me until I make some progress.
