The Keepers have a interesting anatomy. I made one of them in life size [link]
I made the reference for it with lots of screen shots in early 2011. The tricky part was to find the right camera angles because I used only the game engine. The top view and down view was tricky and I couldn't capture the whole body.
Its nice to see someone who delivers artists with reference models. I guess your reference-stuff is mainly for drawings. I needed every limb in a frontal view to get a not perspectively changed silhouette.
I would wish to this reference a top view, a down view and not perspectively changed views of the arms and hands. But except of that, this is a nice template to make a keeper.
Although I didn't used you reference I have to say thank you for this nice service.
