I like it, well for the most part. The thing that seperates a good OC and a great one, really has to do with the flow of it all.
And personally, the color scheme here just doesn't fit well.
Your mane colors are great, they work well together, but the color of your fur and eyes, just doesn't match well with your mane.
But all in all, it's a good concept, those are just my two cents
