Thanks for asking, Boy. My backgrounds are always a mix of vector and raster. I never use photo's in my drawings, that can be the kiss of death in digital work. I will use photo's as a reference to get ideas from for backgrounds but never the photo. I learned many years ago that for digital work it needs to be as original as you can make it. That way you can be far more creative and not get accused of copying. For many of the drawings I do there are few or no photo's anyway. The Shinden illustration above is a perfect example of that.
