I'm generally new to art, and have been learning to paint in Photoshop. One issue I've been running up against is that, because digital tools do not have the inherent texture of traditional media, my results come out too smooth and plastic-y. I'm hoping people might be able to give me some advice on how to overcome this hurdle. To show you what I'm talking about:
I'm trying to avoid too much reliance upon texture mapping/overlays to make my work look natural or realistic. In general, I like a painterly, rather than photorealistic effect, so I don't necessarily need to show pores and freckles every time I paint a face--just as long as the result looks like a painting, and not a balloon. What makes this happen?
I'm not sure if it's my knowledge of Photoshop techniques, or my knowledge or art that's lacking here; that's one of the things I'm hoping you can tell me. What should I be studying in order to reach the next step?
