This looks decent pattern overlay skin whit many changes to the arctic default skin, nice job so far, but lets get deeper in to some points.
Diffuse
The diffuse is much different than the original you decent added camo and almost every other thing has changed like a new body vest new belts, etc...
A very nice job here though why resize to 2048² ? 1024 is large enough for this player skin, just resize it and sharpen it, and it will be good also.
Normal
//Diffuse normal:
The normalmap is just wrong, you just runned the diffuse true a normal map filter, thats not the right way to do, the right way is or hight map or baked from high poly model. Here are some examples:
Hight:

Normal:

Though you always could use the default normal map from valve and merge your diffuse normal on it like i did here:

Phong
If i would made this skin i seriously would apply phong settings, so next time if you make a skin try to add some phong to make it that bit better.
"$phong" "1"
"$phongexponent" "33"
"$phongboost" "1"
"$phongfresnelranges" "[1 4 5]"
"$halflambert" "1"
"$phongalbedotint" "1"
So for this skin i would add this vmt:
"$basetexture" "models\player\t_arctic\t_arctic"
"$bumpmap" "models/player/t_arctic\t_arctic_normal"
"$normalmapalphaenvmapmask" 1
"$envmap" "env_cubemap"
"$envmapcontrast" 0.3
"$envmapsaturation" 0.7
"$envmaptint" "[ 0.36 0.36 0.36 ]"
"$phong" "1"
"$phongexponent" "33"
"$phongboost" "1"
"$phongfresnelranges" "[1 4 5]"
"$halflambert" "1"
"$phongalbedotint" "1"
So ya if you would make a V2 i would add this.
Overall:
Really great job on this arctic skin, some changes for a V2 and it will look great, best of luck and keep up skinning,
Regards Boba Fett.
Here's the pack that i have edited for you containing the vmt, normal and diffuse optimized and resized:
