I like the pants, but the skin and "red" bits lack enough contrast to make the model speak to me.
Hmm... I will be a bit more detailed than that. The skin looks pretty good, but the pastel in the red, makes it feel a bit out of place.
The straps are a bit odd, but nothing a coat of sepian wash cant fix. Devlan mud can be used on the pants, but it may change the color drastically if you are not careful.
"Note"
you drilled the gun-tips.
