Hello! So im really trying to make my hair look nice and this is the best I've done for a long while, any advice on improvements is greatly appreciated as im still very much learning ❤️ (The mane hasn't been updated yet as im focusing on the tail before progressing because i find them easier 😊) The top of the tail will be sorted before moving on.

I just want to say, It looks amazing to me!! <3

Thank you so much! That means alot :D

It looks super realistic. I love it! I literally have no critique to give. Bravo!!

Thank you very much! <3 I find tails easier than manes so hopefully i don't end up pulling my hair out with the mane xD

I think you have totally nailed the hair on the tail!!

The top of the tail looks very well done, however the overall shape of the bottom part of the tail could use improvement. Considering where the horse is placed, and the pose the horse is in, the tail should have more of a shape like the original stock. Consider the flyaways; how they move, where they're placed, and how often they appear. I also suggest taking more of an off-white coloring in the hair as the shadows in the tail currently look a little too dark for the horse.

Adding on, I think you should look where the light is in your background, and add highlights and shadows based on that, rather than where the hair falls behind the legs.
