Infantry squad done; colossus conversion

Finished the infantry squad.  Looks great. Might still add some pigments to it, depending of if I do any on their Chimera.

I plan on using a colossus in the IG army for 'ard boys.  Didn't have one, but my cousin did have a beat up and abused old Basilisk. Going to add something around the barrel, cloth or GS, not sure which.    The tube is 1" in diameter.  Compensating for something?
