As an experienced Photoshop user, I have to say that this is incredibly impressive. PS is typically used by most for image editing. But this is using the PS "sketch and smudge" on a whole other level. Thanks for posting this Cedar - I'm thoroughly impressed :claps:
Choo, the best way to learn Photoshop is to just start playing with it. Open up an image and just start using the various tools on the palette. You'll soon get the hang of it. Take a couple of online tutorials about masking layers and that should give you a basic start.
