Very interesting software. I do like it, took me a while to get my head around it. Mostly because super tiny brush sizes by default... I have two problems with it - sometimes brush leaves glitchy looking, bright color (blue). You can see when you zoom in on the picture. When you actually zoom in inside Our Paint its not there - not like pixels but as blue lines around the edges of the drawn shape. They appear and disappear depends on zoom level. Also the Halftone brush is slow to the point of unusable. Specially on bigger brush sizes. So much for feedback. I will keep exploring Our Paint! Very cool! I see lot of potential!
