I used one of the pics I at my last horseshow for reference. I drew this on photoshop. Her left front leg is not right .. in my reference, Piggy was wearing boots, and I know it is not quite 'straight' /: I will edit it later. The pose was REALLY hard, (I haven't been drawing digitally long, I'm only 13). I really like it though, even though I forgot to finish the two middle hooves. I hand drew it all with my tablet!
Next time I am going to make the base lineart "thinner" so it is not so distracting. Sorry!
Wow that's pretty cool! The only tip I can give is when you are with horses just watch them for a while. Concentrate on every little line and muscle they have and how they move. Engrain it into your mind. It helps lots! Great drawing and keep up the good work!
