Right off the top--the thing that could improve the most about this is that including a full body picture would be great. The gundam itself is looking great (I could have told which one it was, even without the title--thats always a good thing). One thing that I noticed is that this one has exo-force joints for the knees, but it is rather tall. Do you find that it has trouble standing on its own? I built a similar mech frame:
