This looks decent texture for the Desert Eagle, but we will get in to it a bit more.

Diffuse

At first its nice you have 4 version for this on skin, its nice for the downloader he can choose for his favorite color.

Though they are just overlays from the normal silver one they are not bad, only the golden one could be a bit more goldish now it looks like a bit yellowish brown. but for the rest its nice you have done this.

But now to the actually texture:

The main base texture is made of a sponge texture or some kind, its not bad but its far to pixely so i would smudged that out when you where just starting, though some area's are just normal plain color so idk why you used some area's whit the pattern and some not.

As what i can see the highlights you placed are oke maybe bit to strong on some places though i noticed that when its used the area around it is very pixely idk what program you used but if it was photoshop its not on the right settings. (you could fix this whit smudging it)

The main base (slide) is also to much random damage there is a bit well placed damage but still to much random.

Though what i really like on this weapon is the handle the grip pattern is very nice done and also the logo.

For the rest its a decent skin don't know why some say this looked like it was from TS but as i can see its totally not.

Good job on the textures now the other parts.

Normal

Diffuse normal:

Well i must say you used my normal map i sended you but you also merged it whit a crazybump one, so thats bad, you should just make a hight map to the area's that aren't modeled like engraved text or dots etc again here's a better example of a hight and normal, so next time don't use crazybump or diffuse mapping.

Hight:

Normal:

Specular

Well its good that you added a specular map and used: "$normalmapalphaenvmapmask" 1

in the vmt though the specular map should not have light only the base pattern and the scratches, damage you gave it.

Phong

Well you used phong but far to hight for metal + its not a complete setting, so take a look below, though nice job you used my first phong settings i gave you.

"$phong" "1"
"$phongexponent" "33"
"$phongboost"   "1"
"$phongfresnelranges" "[1 4 5]"
"$halflambert" "1"
"$phongalbedotint" "1"

What i also would add (only if looks good)

"$rimlight" "1" 
"$rimlightexponent" "15" 
"$rimlightboost" "1"
"$envmapcontrast" 1
"$envmapsaturation" 0.2
"$envmaptint" "[ .2 .2 .2 ]"

So ya maybe edit this to look that bit better.

Overall:

Very good job on this deagle skin i really like it, though whit some changes its rly good, so for your next skin try to improve that bit more and you will be good :)
