Guys, this is starting to sound like a playground fight, we all have stylistic tastes it's what makes us individuals.
Dither doesn't add to the scaley texture - its just looks a bit more messy. This cartoony dragon does not need overly texturised surfaces, going down the clean aa'd route would be a wise move for this piece. If you do want a textured piece, i would suggest studiying other pixelart dragons, and real lizards and you will see that dither is rarely used to create the main scale patterns.
i would also suggest losing some of the contrast, especially on the face. The arms also look very pillowey.
