For book illustrations or cover art, I mainly work digitally and assure that format, file type and resolution will work for your project. The general process is a draft stage, line art and coloring, then finally I export the files in a format that fits your project.
In that area I also offer professional support for self publishers with layout and book design. I’ve experience with preparing files for e-book distribution, uploads for self publishing portals and also directly for printing companies.
