All painting tools, as to work with textures in the brushes, distortion in the images directly on the screen, I love also feature wrap-around mode and Multibrush tool. There are many tools that enchants me, tools that help me a lot in my workflow.
Sometimes it is too slow in complex work. As an example I can cite when increased much brush size. Sometimes problems with Text tool. Sometimes I have problems with files in PSD format, both to save as opening a native Photoshop file.
Krita has evolved a lot in the latest versions and I see a promising future. With the inclusion of resources for animation I was very excited.
I had a job that needed to have the texture of a painting on canvas, the brush strokes needed to have the fabric texture intervention. It was easy to solve this in Krita, exceeding my expectations.
