So at the moment I am drawing Inside Out, and I just wondered how people get those perfect lines on painttoolSAI. I watched a tutorial and I realised I've done my lineart wrong and filling wrong. I had no idea that keeping my stabilizer on 3 isn't good and I've been drawing on that for all my DA days and filling my lines with the pen tool when I can press Ctrl + F. I'm laughing so much because I didn't realise and I knew something was up with my art. Anyway, started a piece using S-6 and it's much better now. I'll upload it later today.
