very nice Eugene! the blaster is fine, hasbro blasters have permanently attached cylinders, and the build is great.. just a few small things
the side gaps need to be fit better to where there is no overlap
the overlap is most noticeable from the rear
you might need to apply heat or add additional strapping to close the gaps
you can also trim the chest and the butt kidney a little to help align the seams for a better fit. and perhaps you can use foam to fill out the area a bit..
here is a good example to use as a reference for the ab kidney alignment
also position the belt so the split is visible when wearing it normally... note the pic above
and dont forget to add an action shot for you EI profile
