People are always learning. You can not expect somebody who is new with skinning to make a high-quality skin on their first shot, because they don't know how. They always make lower-quality ones, and with proper constructive feedback provided by other users, it helps them improve their work. Your posts completely discourage them from even trying anymore. You should put yourself in their shoes and you would know what it's like.
You need to be much more constructive when you assess a skin. Just disapproving and insulting the skin IS NOT going to make it better. The Author needs to know what to improve upon.
I will permagag you from CSA if you do not improve. This is your last warning.
