you have a habit of drawing dragons with horse/dog type legs, underneath the chest, rather than on the sides, makes them very one directional, they can go forwards and backwards, but sideways movement is restricted. which i guess depends on a persons take on dragons.
it creates the feeling chicken was talking about, that they just dont work in the position, but according to the anatomy, it looks correct enough, looks awkward, but its a dragon eating a watermelon, not much normal about that. lol, i like it.
the main issue are the claws, theyr backwards, dragons cant do that, and thats not a perception thing, they walk on their hands, they do not rotate.
they should be gripping onto the watermelon from the back of it.
nice work overall though, shading on the shoulders and frills around the neck are great
