Rig Critique 2

For this rig critique, I am looking at some gaming assets that people made and posted on the internet. These two I got from CreativeCrash.com.

This next rig I would like to critique was the TF2 Scout rig I downloaded from CreativeCrash.com by user Enkidu13. I feel that this rig was very well done. I did not find very many issues within this rig mainly because certain useful attributes that appear out of nowhere when selecting various control curves on the rig. The few issues I could find were that the auto-stretch system in this character wound up breaking the rig's geometry by inflating instead of  stretching. Perhaps I was using the slider incorrectly, however I could not find another way how I might have operated those functions. 

The second rig I am critiquing is this Megatron rig also from Creative Crash made by the user gary wee. This rig was very simple yet complex in that it reminds me of a transformers action figure that is supposed to turn into a handgun. The whole rig is just fun to mess with, and could definitely have plenty of use in an animation or game of some kind. I personally found no flaws at all with how simple it actually is, although I feel that this character could have more abilities added to it. The only thing I did not like about it at all was that certain control icons disappear into the model when transforming into the gun. The icons disappearing was the only inconvenience I could find that slowed down any maneuvering of the rig.
