I use mostly the default brushes of PS. One really soft for shading skin and one harder for hair and other stuff. But you can come to an similar result using different brushes, it depends more on your skill than the tools you use
I mostly used REIQ material as reference when I started shading on PS. He makes some streams / videos, I think it's a good point for starting
I would like to thank you for helping me out... Whenever I asked the help of an Pro Artist, they all be like " Dude, get your own style" and shit, really, thanks alot! I'll make sure to watch his videos, I really wanna draw like you! Again, thank you so much !
