Top notch! You captured the bulky powersuit look perfectly! Excellent use of pneumatic parts, and I like the tubing at the back of the neck. What backdrop do you use to photograph your MOCs? I can't seem to get that look...
Quoting Areetsa C
If the part on the end of the rifle is some rare pneumatic part, this is very good. If it is something cut or damaged, not-so-good.
It is a very short cut piece of pneumatic cable - something very cheap and common in technic sets with pneumatics. In fact, on each rifle there are 4 pieces, each 2mm long. More rings than cables right now.
Also - even in some lego sets, you have one very long piece of pneumatic cable, and in order to build the set, you have to cut it on your own - so this is perfecly legal technique ;)
