It doesn't look too much like desert. It just doesn't have the desert color to it. As Kagoshima stated, the way you just pasted the camo on the skin made it lose a lot of the minor yet needed details.
Take a look at other skins that reached the Expert class, and look at how they applied their camo. They usually add more details and they break up the camo at the texture seams to make it look better. You should try doing that on your next release.
Also, this is not a New Skin it is a Recolor.
Personally, i don't really like the black dots you added all over the skin - it makes the whole skin look weird especially when you are far from the player and you look at it. Bigger camo spots usually give a nicer effect.
