Hello! I'm Li-ten and I'm mostly a traditional artist trying to do digital art too. I use gimp and still a new with Paint Tool Sai. I was wondering if anyone has any tips with drawing digital (without a tablet). I mostly scan my sketches and open it in a file with the program I am using.
For using a mouse, the stabilizer in Paint Tool Sai is very useful! It makes smooth lines by slowing down the mouse when you draw. It's at the top bar on your workspace in SAI (under the system options like file, selection, etc) You can set sabilizer from 0 to S-7! I hope it helps (*´∀`*)
