this background is amazing. I love this kind of deserts, and you have done it very very nice. Maybe I think that the coach (dont really know if this is the name) is a little big for this mountains, maybe if it would be smaller... but its ok. I also like the anathomy you've used for the dragon's legs, and the color reminds me a lot an amazing comic from france, "Tao Bang", is one of my favourite comics.
its this for any project or something? I't would be nice to buy a comic like this
