Thanks for the tips. I've heard lots about "banding" and have never been to sure to what it was. I shall now read cure's tutorial. Thanks a ton!
The black lineart is missing several places and as colored this would be a technical flaw.
The grey you have used to shade the lineart is too light to have its desired effect here and should be darkened 10% or so. This shade is perfect to AA the most jaggy areas to really make for a better piece. Actually its even smarter to make that shading/AA grey have enough of a pink tone to also work as the lightest flame shade.
*The way you shaded the existing grey is what we call 'banding' which is normally seen as bad pixelling and should always be avoided. More on this in cure's pixelart thread in the forum.
Yes, it is one of my older and quite shittier pieces. Hopefully I'm improving though.
