Thank you so much for the quick reply and detailed critique! I do draw other things than horses, though I view these as some of my better work so I decided to share those :)
In those drawings, I worked from a reference. I do draw horses without a reference but only in sketches, not when I'm trying to get a really detailed appearance with more accurate shading. Here's some other stuff I've been doing.
This was an attempt at ink painting, and watercolors. https://pbs.twimg.com/media/BjBnom-IQAEtdYY.jpg
This one's just a sketch with quick colors. I didn't use a reference which you can probably see since some of my anatomy was a bit awkward. https://pbs.twimg.com/media/BigAUGvIgAA1VTO.jpg
I actually started this one at the beginning of this school year, around September.. But never really continued with it like I planned. But here's a better example of my pencilwork with people.

Hello! Before I get anywhere, I would like to say I'm sixteen, so forgive any mistakes. I've been riding for seven years now and I've been drawing horses since I could remember, so they've ended up being one of my strengths. Anyways, I was interested to hear what people had to say on them. They were done in graphite and each probably took about twenty-ish hours?

I struggle a lot with white fur so any tips on that would be amazing... thanks!!
I'm also looking into applying for VCUarts. Do you think that with improvement over the next year, a drawing like this would be considered portfolio-worthy? I know it's super competitive.
