Though it is quite rough still, especially in the landscape, you can already see it really coming through.. in the scales and how you have painted them, mostly.
The design of it is quite intriguing, I have to say. I like how it works with the setting and how it fits... or rather, how it contrasts in terms of the colour and all so that the lizard stands out quite a bit.
Awesome how the background is shaped there, I think, and the expression of the lizard is a cool one! Looks almost cunning/sly.
