The design makes me think of an MLP version of Toothless from How to Train Your Dragon, except with stunted legs, rather than a missing tail fin. I imagine it must be difficult (if not impossible) to fly with those wheels, and if he can lower his wings to his sides in a similar fashion to how other winged animals in MLP do it, I wonder if they would ever interfere with the wheels while walking around town. I'm probably thinking too much into this.

It's an interesting character, and I love the starry night look of his scales. I bet he's an amazing pet for whomever cares for him and helps maintain his harness.

Aw, that's really cute. I like the detail in the design of the wheel-chair-like device. It's interesting to see a dragon with a noticeable disability, as most pictures of dragons are more focused on being elegant or powerful.
