Those are phenomenal first models. I'm amazed!
As a lizard player myself, I'm happy to see you chose the most awesome army to begin with. They're a lot of fun in the small scale Mordheim setting if you're not ready to take on the full Warhammer battles.
The salamander looks quite demonic right now with the color scheme and the hollow black eye. I'm not sure if you're planning to fill it in, but it's a neat effect right now.
If you manage to paint everything you get before buying more, you will have accomplished the nigh impossible. Good luck.
