*critique wanted!* coming back home to you

as sure as the life in the garden that you grew

i'm always coming back home to you

I am in dire need of some help with this piece! I had a really difficult time finding and choosing stock to work with, and I'm not completely happy with my choices... however, I don't really want to start all over right now (maybe eventually, haha).

Here are some things I could really use help with:
Hair - the tail in particular looks like poop I painted over the original mane, so only 90% of that is actually my work tbh.
Shadow
Reflection
Light source - I think it looks alright since there isn't really a strong light source, but I could probably still do something to make it look even better lol.

Things I need to fix (but don't necessarily need help with):
Eyes
Leg to water blending - don't ask what I did here, I'm not sure
Leg feathers - I wanted to add them to the horse, but I got lazy/forgot about them... just making a note in case I want to take a go at them later!

Any help would be very much appreciated!
