Pretty Nice.
One or two thing I could recommend.
1. When you really think your done add a wash too the models skin if it is a blue wash or a brown/black wash all over the model just to add that little bit of shading.
2. This is personal preference really but I think the Stegadons Howdah looks better painted stone or gold rather than silver, but don't pay too much attention to that because as I say, it's just personal preference really.
Apart from that their looking pretty good and I admire you for managing to get a whole army painted (I paint really, really slowly).
Keep up the good work, Bez
P.S. I really like the way you have used the older models in your army, I have the old Skink Priest and one older Kroxigor but that's about it.
