I dont have the back gfx piece for my camaro(the bumper cover and short piece on back fender) will it look odd, post some pics if you have any...

 

What are u asking here??

 

If you are saying you added the side gfx and iroc style nose, but not the back, then I'd say yes, it'll look cheap and unfinished imho. But if you are doing it in stages and plan to add the back pieces when you get the money, then who cares if it looks unfinished.
