As most of the people here know, we hate certain things. There's no need to expect 20 replies after the first night since you post. That is just one of the examples, the others are:
We don't like packs that use generated effects such as "noise" or "blur". Your pack needs sharpness and shading. If there is none of this you'll have to deal with a few pages of criticism.
We here at the Texture Discussion also don't like the "slang" that you may use in other places. For example, if I were to post a pack I wouldn't say "OMG! PLZ downloadz PLZzzz! My firzt pack!". But instead say "Minecrafters! This is a very good pack that I have made in my spare time and I hope you enjoy. Please download, and thx!".
