I hope you realise, a long time taken to reskin doesn't automatically make your skin great. The way you've made your notes, makes it seem like you've put a tonne of effort into this.
4 out of the 5 screenshots just show the logos. One of them shows the side, which in truth, is pretty pathetic. You took Evildaedalus's skin, took a part of it and made it a still skin. Followed up by placing a logo or two onto it.
The biohazard symbol and theme has been done already. The team logos are being done as well, see "Team uniform pack." No doubt they'll be some kind of weapon one.
Congratulations you corrected the phong, at least I know you put some work into this.
Also I've noticed you're taking parts of good skins, and remaking them. Yes you're giving them credit. Better than just stealing it, but it's only the least you can do. I hope you've contacted and asked etc.
I'd be pretty pissed if some one took a part of my idea, slapped on some credit. At the end of the day, you're the one getting the downloads and ratings. And I wouldn't even know about it. After all some people might not want their work released by others.
For what ever reason, be it personal or just would prefer to avoid having their work associated with others.
I could be wrong about the credit thing. Since I don't know for sure. Either way my rating stays the same, since in terms of detail and texture it's hardly different from the original. Model is the same as Valve's and adding realism isn't really a good idea.
