Just plain good.

I’m not a very talented artist, but I love this app. Having multiple layers really helps when I’m sketching over a photo, or just want to draw without worrying about messing up something else! Having different brushes is also really neat. Little details and shading are often really difficult in other drawing apps, but being able to paint like in photoshop, it’s much easier. I’d really recommend this to anyone, even if you’re not an artist!
