Texture - 9/10 The texture itself is very nice, lots of extremely minute details, but I'd like to see more alternatives of different textures (e.g. black).
Model - 9/10 The model of the gun is what makes it special from the other AWP skins in CS:S because this is the first ever MSR skin to be released (not counting the illegally ported one). However, it has no world model which I believe you are working on.
Animation - 8/10 I'd like to say I don't download skins when I don't like the animations (I've tested the skin in-game btw, I do not criticize without trying it firsthand) even though the model is the best model I've ever seen, but this one is sufficient in my opinion. My only issue is with the draw animation, particularly the first draw shown in the video (the "from the back" draw). It feels somewhat unusual to "grab" the gun too soon that it shows the sleeves of the player.
Originality - 10/10 As I previously stated, this is one of the specials in GameBanana, or at least, in CS:S. Very unique, and compiled by the one and only.
Sound - 10/10 I am not as extreme in sounds as in animations, so I don't have an issue with the sounds used in this compilation.
Realism - 10/10 As all of your skins are, this one is no exception. Although I don't have my own MSR in real life, it looks no different from what I usually see online.
Functionality - 10/10 From the testings and examinations that I have done (I just played with it, lol), I haven't found a single issue or error with the compilation.
Detail - 9/10 The texture of the skin is real good, but I find the detail in it to be short-handed (e.g. Remington logos).
Overall - 9/10 This is absolutely one of the best skins I've ever found. The pros exponentially outweighs the cons of this skin. I don't regret wasting one hour making this reply, as long as you read this, I'm already more than happy.
