@Phemto  
im no good with color mate, but if i were to suggest anything, as weird as it is this: http://paletton.com/#uid=32A1w0kfcsB2hVC8gF6m6lmuVch could suffice

Thanks for the input. I think you’re right about the back legs.
 
In fact, I did use a reference, but it wasn’t a cannon pastel pony. My intent was to create a different art style, rather than just reproduce the models that already exist. I’d call this style closer to the MAS series than the canon one.
 
At this point the wings are the only thing rigged. Their rest pose is horizontal as recommended by about 80% of the internet. The other 20% likes palms-out and talks of jihad. My placement of the joints in the wings were somewhat constrained by how he’s going to use them. It’s important his “thumbs” not be to far forward when the wings are in. All the metatarsals and phalanges are parented to the “palm bone” and weighted to fold smoothly, and the wings can close fully against the body without obvious clipping, but the shoulders need some tweaking to look more natural when they do. I’m going to have to create some shape keys for the closing action so it’s not so involved.
 
I kept the topology all quads except for the eyes. They’re UV spheres that have been mesh-deformed so that he can look around. I’m still amazed that it even worked.
 
Thanks again for the advice. I’m still not convinced of the color scheme. As suggestions?

Interesting to say the least, it appears you have not used reference images for the proportions of the pastel horse, also the hind legs appear to be way too close together in relation to the front legs, this is a bad T pose.
 
As for the front legs, they branch off from the body too far to the middle, this will most definitely lead to rigging issues when you get around to animating.
 
nothing personal or with intent to be mean but i suggest you recreate the model from scratch this time using LEFT, RIGHT, FRONT and BACK reference images like so:
 

 
But obviously with the ponys design that you are creating
 
Also the wings branch way too far off to the side of the model, i would recommend having them at more of a 45 degree angle, this would help with rigging the skeleton eswell.
 
Overall though the model appears to have good topology as evidenced by the smoothing, it just needs improvement on the placements of parts that are to be rigged and fixing up on proportions
