Sure, many repaints have some retools meaning a new head or even another new part. Still, some of the molds are just too similars. Well, maybe you have done it before, but just MINOR MISTRANSFORMATIONS CAN MAKE A UNIQUE AND BETTER LOOKING CHARACTER!
First example, my Alternators Shockblast. From the start, I dont really like how his feets look and I'm receiving Alternators Jazz soon with a Reprolabel sheet so he will not be looking like his own character.
Here's what I'm getting:

Jazz HAVE to remain properly transformed as shoiwn. This IS Jazz.
Still, that Shockwave is a little too similar:

So, I just removed the hood and the muffler (he already have a gunarm) and place them in his backpack. Also, his doors have been laid back. It make for a bigger backpack, but I think it improves the look.
Finally, his feets are backward. Just some twists and turns with the legs, wiast, and feets did the job. The feets in this way look WAY better.
Here, have some pictures:





See? Shockwave look more like his own character rather than just a repainted Jazz.
Now, do you have some repaints you slightly mistransformed to make them more unique?
Please post pictures!
