Here's what I see:
There is a problem with readability caused by tangents. One of the horns and the lower body, the rear leg(?) and the shoulder joint, these all run into each other.
From Thumb War (

Overlap // Overlap shows what's in front (outline thickest around things closest to you) and what's in back. Use draw-through to get overlaps correct. In addition to giving you cheap dimensionality with a minimum of perspective tricks, overlap frees you from drawing whatever is obscured. Often the viewer will fill in those obscured details themselves. Pay attention to overlap that occurs WITHIN objects. Make all overlaps obvious to avoid tangents : lines/objects that appear to touch or intersect awkwardly, weakening your depth illusion.
The shadows on the tail don't match the shadows on the body.
I can't tell what those ridges on the center back are. Seats? Scales? Coils?
It's kind of odd to have one wing edge on and the other almost flat to the view. The visual masses are balanced by the head and tail, it's just a bit odd.
Overall this image is ok. I don't think you can get a lot of texture detail at this scale, so maybe a use a few representative scales here and there instead.
Hope this helps,
