Hey, I'll be doing Narnia artwork at this one theater, voluntary work. The downside is I never done painting on glass before so I'll like get some tips from you ladies n gals. Here's my steps and please correct these if you think its wrong or whatsoever. 1. base color paint 2. outlining with pencil 3. Basic color painting from top corner to bot corner 4. Add shades 5. refine 6. detail 7. lighting 8. highlighting 9. Spray with special product to keep it from wet, decay, etc. (dunno what kind though) 10. Take pictures, show off to the internet and will be part of my portfolio. And How would I add almost transparent paint to the image? I have done digital painting for awhile and that's pretty easy to do but for traditional art, it's way different, that's for sure.
