The banner is an old bit from the Nurgle Planguin model. Which I have, but I also acquired 2 or 3 of the banners from GW bitz when you could get them at Grand Tournaments.
I too wonder if I should have went further with sand or putty, but I didn't want to obscure the model's feet as they were already fully painted. Same reason I didn't want to bust off or cut off the existing bases. They look better and I think on the table no one will notice it much.
I should take more pictures of old models, especially in squad poses, as all my figs are gaming models... I gotta paint my Lead Painter League entries still, but thanks for looking at these, a lot of work went into these 11 models...
