Oh!... Quite a lot of art here, actually the drawing is already excellent in the original natural format. But those additional edits you made are very good and allow us to appreciate the same work with different colour schemes and lighting. I've always found this hybridisation of handmade art with the facilities of the digital world to be a delightful thing. All the results are excellent as I said, but I'm especially attracted to the last one in that "almost sepia-like" tonality... Thanks for sharing!
