Thanks all for the nice comments... :o)
About the bone color.. the base was Vallejo 921 English Uniform where I have added more and more Vallejo 976 Buff for the highlights.
For the final highlight I have used Vallejo Buff and Vallejo White in a 50/50 mix
I'm scared of howling banshees................ they slaughtered my assauly marines first and then my 10 man tactical squad, that's 15 marines!!! (btw, very well painted!)
