I really like that first horse one! I think you captured it very well. =)
This one will probably be pretty challenging if you decide to do, atleast it would be challenging for me! =P
This one probably wouldn't be too hard.
Here's an interesting angle... It'll probably be super challenging though.
I love this picture and it probably wouldn't be too hard.
I did this one for my art class, it'd be interesting to see how you did it, if you wanted to try.
This is how I did it (I'm a painter though so I painted it) and it's a horrible quality picture but you the idea. =)
And if you feel like a whole body shot without movement, here you go.
I hope all these pictures aren't too overwhelming! Just play around with them and have fun! I can find the bigger copies of them if you need that, I just didn't want to make them too huge, yknow? =)
