Yes,that's what I thought, having seen that work you did all in one layer. You seemed quite happy with yoursel, so I assumed it is hard to draw with one layer. though I do appreciate the help, greatly! If you have any more tips, I'm all ears,@Aura!
All good, it's all up to preference after all! That's why I found that other guide. I kinda respect that you work without layers though, I find it really hard to do so I guess I think it's just cool when other people prefer it?
Okay, FireAlpaca has layers, so if you have the linework on a layer above the colour, those pixels should go away (provided I'm correct about what's caused those pixels anyway). You might have to colour it manually rather than using a paint bucket or something like that (unless you select out the area first with a lasso tool and then fill it), but it's not too tricky to do. Alternatively, I found this little guide to dealing with antialiasing so you don't have to worry about layers too much.
This is pretty cute, good job! Although I think you could improve the quality a lot if you got rid of those white pixels around the linework. What program did you draw this in? I might be able to help you out with it.
