Thanks for the comments so far and honesty! Much appreciated. They will only help in making improvements, so it means a lot.
I am totally against Optimus' flames, so I guess if I did that it would be supporting the flames, eh? HAHA!
If it was gonna be flames it would be like a silvery transparent look, but I dunno. I'm already borderline going too far into the geek realm, but I'm not trying to make it a "TRANSFORMERS BRAND" by slapping that name over it. Sure the whole Decepticon lettering is already more than what a standard vehicle should have on it if it were a real decepticon, but most of it consists of emblems.
I saw this truck today and kinda link the idea behind the design of these lines and how to incorporate it in the graphics on the side of my car:

One is choosing color scheme and 2 is making sure it isn't too busy. My current theme has just been a silver and black theme, but would be nice to but in a dark purple or a blue sort of thing (?). I will be doing photoshop renders to see what's going to work or not. The racing stripes, while cool, is on many cars and I want it to be more unique, although I get enough eyeballs looking with the emblems as it is to be unique. This is so difficult to decide... I might find those lines would look lame on the sides... well I'll see..
Thanks again!
