i just finished with my second CD. the beard started out defined, but i made too much GS and i didnt want to waste it, so i continued on the whole model. its gone semi-flat. most of it will be covered by a BB so it won’t look too bad. my mask attempt looks like its sloughing off though…i suck at gaging the amount to knead…
Whatever works for you really - I try and always use a fairly limited palette when painting so i would pick something that complements colours you are already using
I like the whole multi-colour beard, Khan!'s army is really cool, also try blue, purple, white and why not mix the colours too
It’s hard to guess how much GS you are going to need and even those who ave been sculpting for years don’t get it exactly right, so don’t be too bothered about that. You can get alot more Green Stuff for alot less money on eBay, GW are ridiculously priced for the amount you get.
In my classic army I have a lot of different colours but in the new army I’m doing all will be black with blue, purple, grey and yes, turquoise highlights.
In my opinion the colour of the beards depend on your army style.
BigHats are predestinated for a more uniform colour scheme, the old marauder ones rather to a more chaotic and particular one - to mean more colourful and not compulsive realistic!
