A general question, all of your caps are gorgeous! I've just tried googling editing tutorials but I can never find good ones, and I was curious. :3
Thank you! This is allshallfade. I can only speak for myself, but I never use textures on my caps. The best advice I can give you is to experiment with whichever editing program you use until you find a technique that works for you. It took me a long time to be comfortable enough with Photoshop that I’m usually pretty satisfied with how my coloring comes out. I’ve never used tutorials, I’ve always just experimented. The settings I play around with the most are brightness/contrast, color balance, hue/saturation, curves, levels, and selective coloring. I also use various color fill layers and duplicate layers on different settings. I’m sure each one of us has very different techniques for achieving our final results, but it really is a matter of experimenting until you find what works for you!
