Here i have adapted my Mark I prototype, enhancing both the legs and arms/body. This make over was brought on by comments on other APU's and design/photos i found on net. Realising legs bent in the wrong direction, and arms weren't hunched enough.
About this creation
Here you can see the difference made to the arms/shoulders, by creating a more hunched impression
The original MkI design is on the right.
Here the legs were redesigned, the MKI version (right) was too tall, and the legs bent in the wrong direction. Enhancements also made to 'toes'. The base was also design to rotate on a single turntable opposed to the MKI which employed two independant turntable.
From what I can see it's very good, but man, the photography, the photography!
I'm no expert in photography but I do now that it is every bit as important as the MOC... I mean, it takes alot of skill to <i>build</i> an impressive model and it takes just as much skill to <i>show</i> a model in a way that people can interpret. I find that the best lego builders out there can not only make a good MOC, but they can also take great pictures.
Firstly I suggest you steady the camera... motion blur in a picture is always bad. secondly, I suggest you focus the picture if you can... out of focus pictures don't tell a story very well.
I hope you take this in the way it's meant and not as an insult. I like the look of your APU but I just can't see it that well.
