This here is Indigo Shadow an OC of Michael M. (or michaelmaddox222 f you prefer) who does some pretty good work (if you like straitjackets then he’s definitely someone to checkout).  
I actually made this pic on a moments whim when I came across a pic of her the other day. She’s got a nice design and an interesting mane style that I wanted to try my hand at. Her colors are based on her scarf and glasses since her headbands colors are so similar to her coat and mane and I think the colors look pretty stylish on her. The background is a little plain but I think just adding the pictures gave it a big boost (especially since baby pictures are adorable).
