Thanks for the feed back to those that left comments on the previous post. I have just put together the models and must say they are absolutely amazing, outstanding detail on each model, which brings me to my next problem.
They are so detailed that there is no space really on the model to add any more detail like scales for the Alpha Legion.
It seems the best way to go would be to look purely on the paint scheme and not the modelling potential. I am not sure that doing Company of Misery or Knights of Blood would work on these models because the flames and or blood would be obscured by all the existing detail. Same for Claws of Lorek.
Schemes that could work could be Thousand Sons, Nightlords and Reborn.
If you know of some other examples I could look at please let me know as I have not seen much on the net or if you have any other ideas let me know.
Thanks
Vitor
