Pros: The green texture on the side is a neat departure from the standard Soldier rockets. I'm pleased to see that you didn't make every part of it a solid green, leaving a bit of detail in the wake of the reskin. It is very unique, and fits the Soldier's 'Pro-American', 'Gung-Ho' mentality with the teeth.
Cons: The skin is too clean - the green looks too solid, and pristine, and the teeth decal is way too bright. There is little to no shading or shadowing on the Direct Hit's body, making it look like it is fullbright with phong mapping.
In a related note, there is no shading underneath the edges of the scope's mount, either, making it look unnatural.
Improvements: The skin could be roughed up some more. This DH looks like it came straight out of a box, brand new, especially with the teeth decal, and these details make the weapon too bright. These key factors divert the eyes to the weapon more than the combat.
Also, you may want darken the areas near where peripherals attach to the gun - the scope, the grip - and near the bottom of it in general, to fix the issue of the unnatural shading.
Notes: This is a decent unlock reskin, and impressive by design. With a bit of work and modification, it can be substantially improved.
