The middle photo shows a different angle of the saddle. You can see how the thickness of the boot affects the size of the stirrups. The saddle had to wait until the boots were perfected.
In the last photo my soldier ape mimics a screen shot taken from the original movie, Planet of the Apes.
The only thing missing now is a complete bridle. Oh...and I have to add some scuff marks here and there especially on the saddle bags to make it look less new. That's a minor future project.
