I can see from the picture that you spent a ton of time on the Lizard mounts and the base. To me the chariot part doesn't share the same level of work. and without a driver it looks like a runaway. But it is very nice!
For a Slaaneshi chariot I'd be tempted to lighten the wood a little, but that's a personal choice. Definitely do some work on the metal, though. It lacks any tone or shading and looks too bland at the moment. Again, this is all in my personal opinion. On the plus side, i like the beasts, and the fur cloak looks good as well. Will you be doing any penants or banners? They would look nice fluttering from the spears you have on the side there. Look forward to seeing it finished, and hope the comments come in useful.
The picture is very bad, I reajusted the camera settings and i didn't realize it since i posted the photo... that is the reason it looks so grainy, I'll post a better pic when I get time for it. Not concerned about the rating, I'd like to hear your comments.
