Quoting Colin Small
Wow! I love it! What pieces did you use to make the twin-linked blasters on the left hand?
If you want to inspect it for yourself, you're free to download the LDD file and break it down. I used SNOT techniques and a pair of long pipes with standard rods coming out of their bases. They resemble stagger rifle barrels (and solid fuel boosters), so I used them to make something that resembled the ZZ Gundam's twin mega particle cannon.
