i think that no one is posting because it is something that has been done before, and it is something anyone familiar with photoshop's tools could make
i am not trying to make you feel bad. however, if you want a great response from the community, see what people are wanting and make those unique textures.
metal with blood smear, it just isnt that unique you know
if you did make a lot of unique textures, apologies. wheres your texture pack?
keep working on your texturing. what i am saying is that, while the texture certainly isnt bad, it isnt GREAT. so, i would say keep working on finding new cool stuff with photoshop's tools and such, and soon enough you'll have an individual style etc, and be cranking out awesome textures
but even then, i wouldnt buy your texture pack, cuz i like to texture my models myself

(and make my models... and code... and sfx... no wonder i have not finished a project!)
