no offense or anything but i think the energy sword on looks really ..... um ..... unprofessional. Try and make onjects jojn together. the sword is obviously just stuck behind the gun. Have a go at making it part of the actual gun, e.g. "emitters" of the energy "blades" (one above the barrel, one below).
All the others are good but try to vary the bits that are copy and pasted and don't mix covenant with UNSC (unless the humans want to create a hybrid and even then, it would have varied parts)
