Man I love arabians xD Keep in mind that I tend to slightlyyy hehe stylize a bit and I'm not really an expert, but I'm happy to help!
Alrighty! So rocky you've got a great sense of the square proportion for horses, though to keep the barrel balanced with the body I think you should bring it down some to make room for the ribcage, along with bringing down the stifle and elbow. I think that lowering the breast point and not making it as rounded will make the motion seem more fluid, though overall the movement of your drawing looks pretty good so don't worry too much lovely<3 What I think you should really focus on is shaping the limbs, the way you did the body is excellent, but the legs in my opinion are what give a horse its' fluidity. Hmm I'd suggest really rounding out the hindquarters and giving the horse more forearm and gaskin(?) and making the canons just a bit shorter. And always keep that hock slightly higher than the horse's knees c:
With arabians I kind of tend to make the neck really curvy, which you can do or not do, I think it just gives it a more arabian look hehe
If you want to make another drawing and want it to be redlined, I'd love to help out and see how you improved!<33
