Thank you for your response! I am totally new to fractals. I hesrd about it few weeks ago actually but it is something I am interested in looking into. As for pixelated art, I started in late August this year and it can be quite fun but shading can be annoying on bigger canvases (atleast for me it was tedious). I am currently in the pursuit of getting a tablet as well to make the workflow easier.
I have heard a lot of positive things about Aseprite as a solid choice for making pixelated art but I personally did not use that.
Pixel Studio is pretty good, can cloud save between tablets/phones/pc etc. The canvas size is a bit limited, but other than that you can do a lot with it and it works well for multiple devices.
