Meow, Rontu!! I'm so happy and flattered that you've checked my work! I'm honored!
First I edit the brightness/contrast etc in Photoshop Lightroom, then I export the image and edit it again in Photoshop Cs, just create another layer and set it to normal and use the brushes set to color dodge or overlay for a softer touch of light! ^.^
I do this because I want to be better at both traditional & digital painting, so I kinda paint each drawing twice..plus it's kinda hard for me to create neat linear art in photoshop, so I went towards experimenting light effects. I didn't even know if I could do this, but so many great people asked me very very nicely to finish it. I'm really happy about the result, and I rarely am.
