@spazzy, I was thinking about some sort of winter base, but not sure what, you have any cool ideas I could borrow
@ Dammekkos2, just checked your gallery some nice marines in there! anyway this is how I did the skin, will try and explain it step by step.
#1 spray white undercoat.
#2 Then I painted the whole skin area with scorched brown, 2 thin layers, or until the area has a even base coat.
#3 Next is to completely cover the scorched brown with dark flesh, again I covered the whole area with 2 thin coats.
#4 Next I layered thin dwarf flesh on the model, to bring out the shape of the muscles, its best to use really thin coats at this point. I did 4 or 5 coats.
#5 now mix elf flesh with dwarf flesh and layer again with thin coats, keep adding more elf to the mix until your using pure elf.
#6 Now the scary part, I read somewhere on C\'mon that its best to use a blue wash to make the skin look more real, so i did and phew it worked, use very very very thin wash of shadow grey, wants to look like pure water your using, with a blue tint, using thin coats, dont overload your brush, make 3-4 washes until you see a blue tint in the shadows, then do the same with dark flesh.
#7 now the highlights, using elf flesh, start to highlight, again thin coats is the key to keeping the skin smooth, I then started to add small amounts of bleached bone to the mix, until it was nearly all bleached bone I was using.
#8 last step another very thin wash, this time of elf flesh, just to help blend the highlights in.
thats it so far, if anyone can improve the way I am doing skin, give some tips, ideas that would be great, made it up as i was going using a few different ideas that I have read on c\'mon.
thanks again for your feedback.
