I built a better looking sideswipe with the torso being a mcdonalds 2015 sideswipe I also used warrior class sideswipe legs for the new legs and for the waist I cut and used rid primes ko back and vertabreaks head was from gold fire grimlock and I made a amv video on how cool i think vertabreak and sideswipe are!
I'm not sure how i feel about the pieces together nature of it (unless thats the parts you had, in which case thats fine) but I like the use of Grimlocks head for vertebreak. It could really use a repaint to sell the idea, though.
