I like the way you did the shading on your drawing ^^ The eyes themselves look good too.
Thank you! I didn't do so much shading aside from faint lines on he farther esr. But those disappeared after I edited the photo.
Filthy Rich's design is similar but I like your character design more. The way you drew the face itself has a cool look to it and your character's ear has a different shape.
I'm not too good at drawing stallion head shapes, so I'm glad of how this came out.

And as for the ear shape. I usually use the cupped style that's been used for a while (a good example of it is from the MLP movie), though I'll occasionally use the smaller, triangular style that's been used in the past genetations. And that statement regardong Filty Rich? Are you saying this is him? Or like what. It... Just came out as weird to keep the way it was put.

You are right , they do look similar. You did a cute job.
Thank you! And yeah, I remember somewhere on DeviantArt there's an artist who does vectors of characters with colors pallates of other characters. He did one of Caballeron with Filthy Rich and
my god. Aside from a brighter coat, no stubble, blue eyes, and the light gray areas missing— they are nearly on part with one another.
