request OC Suggestions for Shining Star?

[MissShiningStar 33]

I need a new design for my OC, Shining Star. Here's some background info:

 

Shining Star is an orphaned unicorn pony who didn't even know she had a horn until her teenage years. She has only just found her horn on a river bank and had it implanted on her by a surgeon. She is still trying to unveil the true potential of her magic.

 

Color suggestions: Brown coat, darker brown mane (possibly with streaks) and a sweet, endearing face.

 

Any suggestions for her cutie mark?

 

Also, if you have any more tips or could draw an OC for me, that would be awesome.

 

Thank you all!
