I was wondering what you guys thought of my art of my newest EEE. Is the credits ok?

You need to work on scale so the horse fits with the background And work on hooves other sit on the ground/surface

Credits look good to me. :) I would work on making shadows. It will make your horse look more grounded and give the images a more realistic look. :)

Maybe try and play around with hues and such to get the horse to better fit the background colors and vice versa. Also maybe try and find backgrounds and horse poses that fit well together :)

Credits are fine - greyscales and precuts can be more difficult to manipulate in terms of making them look natural. Work on tinkering with hues/color balances so the horse and background match in tone.
