This is my first creation with Krita, I downloaded it and jumped in without even reading the manual or watching a tutorial. It definitely has plenty of powerful features, a wealth of brushes, and the interface is easy to work with ~ I highly recommend it, and I am adding it to my drawing and painting arsenal ~ check it out at: https://krita.org/
