Hi! Thanks for your interest. Seph is a main character from a novel I'm working on which I will publish in the future, however, I'm currently working on publishing a scifi series so there is no where to find her story just yet. If you're interested, though, you can keep an eye on my gallery and I'll post updates about my books, etc. I can't give out too much info on her backstory yet because it is so important to her book.
Thank you for your questions! I use Photoshop and as for the hair, I start with painting the general shape of the locks, with a big brush, then I start adding shadows and lights, with smaller brushes. I can also use 1 px brush if needed! ^^
