I like that old skink in the front he looks venerable, the old models are kinda neat to see again, would like to see more pics acctually.
I think they're coming along nicely. Maybe try using some of the citadel washes, and a little drybrushing of different colors, especially on the bases.
Some of those later skinks look absolutely fantastic with the deep blue and bright orange! Great work. I have a single lone saurus like the old ones you have, it was about my first model free with a white dwarf (along with a marine termie), they were great! Good to see the old stuff kicking around and still in use. I agree with the people saying inks on some of the models would make them much better.
I also think that the bases could use a little work, but the models themselves are coming along splendidly!
Thanks. I got some old temple guard, an old Slann, an old Terradon and an old Salamander in my army as well. I should have some more pics soon, as the tourney is next weekend, which means I have some serious work to do.
