* Those that simply praise without any word of improvement.
* A lack of response, usually the result of either little exposure of the art to the public, or the lack of ability to constructively criticise or analyse.
Much of my pixel art activities are currently concentrated in Pixeljoint and Pixelation, where attention is paid on good pixel art techniques and comments & criticism. I will still submit pixel art here as a matter of courtesy (since dA introduced me to excellent pixel art in 2003), but there may be a few changes with regards to the type of comments allowed.
Guess the guys in Pixelation where right a long time ago (sorry `ShoneGold). dA has always been one big popularity contest.
