I can't really see too much of difference on the Screenshots,So I had to download the skin to see what Changed. And well,It changed some things,Some on there,and some on the another part,So yeah,I have Half-Life 2 Installed and I have the Default Texture of the Hazard Environment Suit,But they're all separated and the screenshots won't help too sometimes,So maybe you should take a Picture on the Half-Life 2 Model Viewer,That you can find on the Program "Crowbar" by Setting up the certain Configurations. But I see that changed something,Like the Gloves and a bit on the HEV Sleeves but isn't a Big "Change" But as a Good Phrase of a Gamer: "The Good Ol' beta/alpha Things". And I approve that Phrase.
On a resumed way: On Terms of Texture,The difference isn't all that big.
