So I made a quick pone with your base ideas. Soory, I didn't have hazel for the eyes.
So here is what I came up with. I also made the mane more crimson.
I like the design. The cutie mark I think is special though.
Well thought out and pretty intuitive.
I might draw your OC at some point, is that okay with you?
I'll message them to you. I won't post it anywhere so you can do with it what you want
These are very good!, though like @PhantomFilly said, the third one is also my favourite.
And the pony with the hat.
And the one with Celestia and Luna.
You know what, I like them all!!
If you get the chance, could you draw my OC Sylvester?? I shall attach images to this post.
Also, if you feel extravagant, you can do...
But don't feel obliged to. These are merely ideas i am throwing your way
The hind leg looks a bit out of place, I think the flank should be a tad bit higher.
But it is a nice and dynamic pose, which is awesome!
Also, a very cute OC! I like him already.
A brohoof to you!
I really like the new OC concept. Don't ask me why it just looks cute :3 Very nice work! Have you constructed a personality and storyline? If so I would really like to read it
