Wingless dragon

ok here are some suggestions on the main issues I see: 

1. the feet closer to us (left front and left hind) should be in the same height unless the ground is leaning (the posture in this piece suggests the ground is straight)
2. The hind legs should be thicker, mainly in the thigh area
3. the shoulder on the left front leg seems a bit too low
4. the head feels disconnected from the neck

Here I fixed those: 
And in my personal view, I would fix some smaller issues like this:   most of those are subjective tho.

Remember, references are artists best friend. google pics of dragons, wolves, big cats, as the person below said, even horses, it depends on the type of dragon you want to draw. If you feel unsure about poses such as this one, I suggest you practice side views and front and back views first, to get the basic idea of what shapes to use for the drawing. Later, it will be easier to put those shapes into perspective. References in a similar pose (if you can find one) would help too.

I hope this was helpful, and good luck! <3
