I appreciate the comments from all of you. I will work on the beard color, after looking at it I will attempt more contrast with the hair color, I agree it may be to "montone" and need some refining.
For the ice effect, I did take a bit of an "artistic" approach with it. It may be a little extreme and over the top, but that being said I will say it looks better in person than what my poor pictures portray. I used heavy gel gloss medium tinted with some white acrylic color to apply it and it does have somewhat of a tranluscent feel to it. I know it is an often used "cliche"...but I think the effects are better seen in person than here in pics.
As Nick shows in his pictures and having lived here in the frigid state of Minnesota all my life, I can relate to having some ice and frost on my beard quite often when working outside during winter. I have read that the temperatures were very cold, reaching as low as 30-40 F below zero at Chosin where this marine is portrayed to have been, so he would understandably have some ice and frost on his facial hair at those extreme temps.
Adrian-the rifle was painted by airbrushing the grain effect with a stencil first and then giving it oil washes and streaking after the acrylic had dried.
Once again thanks for the critiques and comments, this type of discussion helps in the process of improvement and is truly appreciated.
