Good job on the model, the bleached bone armour looks great! If you're using him as a test piece for a Lizardman army, I hope you're planning on a bit of highlighting on the red.
The wash just doesn't seem to make the cape stand out, and the blades definitely need a highlight for some real depth. The Lizardman army should look pretty nice in a scheme like that, can't wait to see the start of them!
