"Yandorian ranger" by Dave Edwards

You can tell I like rangers... Right? I absolutely love the picture.. it is perfect in proportion and shading, and just about everything else too!

This is a GREAT picture, and I loved the shading! No, there isn't anything wrong with the shading, you may be assured of that XD

The legs are too long and out of proportion with the upper body, and also it would probably be a whole lot less scarier for the rider if the legs were adjusted. In general, the rider looks too relaxed--loose reins, loose legs, straight body. Of course, if she has a good position in the saddle, she probably wouldn't topple off like I would, but if the legs were shown to be tight against either side of the yandorian, it would look better (to my opinion).
That pretty much sums it all up, except maybe that the head looks a little funny (just the shape, the features are fine). Anyway, great picture!
