Not bad stuff!
I can see some anatomy issues, particularly with the horses (which are a PAIN to draw D| ), if you'd like I can redline a couple of these for you? c:
Also, I highly reccommend some life-sketching! Grab some photos of some horses or wolves or whatever you feel like drawing and sketch them out to get used to the anatomy. You can also use 2-3 photos as refs when drawing to figure out where the limbs should be, I do that often and it's invaluable!
Another tip, when shading don't use black or dark gray! It makes the shading generally appear rather flat and boring (not your art! Just the shading colour.) so you should use a colour that blends with the light in your image.
For example; at night use a dark blue. Midday on a bright sunny day use a light blue. Autumn use a darker brown/orange/yellow colour. Don't be afraid to mix up colours!
Colour is a valuable tool when making an image really pop!
Overall I think you have great potential and with practice you can make your art even better!
Wow!!! Thank you so so much! I'm really happy to know you think those wonderful things!
