Yes I only use oil never add anything digitally :)

Well my personal opinion is, that someone as talented as you look thus far, would be GREAT at using digital tools... I mean, Photoshop, Illustrator, SketchBook, even this online tool named Canva, would be at your feet... But of course, those take time and dedication too (except maybe the last one xD), so if you dedicate yourself fully to oil painting and are settled with it, so be it. :D Happy new year to you! May 2018 be full of blessings and many more of your masterpieces, sir!

Actually I am pretty proficient with photoshop and other programs, it's just that I don't use those tools to enhance the oil paintings that I create :) Although if I need to adjust the "levels" I will use that.
