nice modelling but from a design concept car stand point its not the best car in the world dude.
firstly the door doesnt look like it actually finishes at the bottom end there looks to be no sill which really not a good idea because that means the whole car would fall in on its self.not good lol.it also doesnt look like the car has any waistline or shoulder lines may want to look at that.
the front looks alright not amazing need some work on the headlights but then again some concepts lately are very similar.
the rear well the first rear i saw was a bit against the theme if you know what i mean.i saw the word hybrid and then i looked at the render and so two huge exhausts glad to have seen those go.but the rear which you have changed it to well first the lights need to be changed because the really aren't nice.the lower bumper line needs to be changed because it looks unfinished and the over hang is out of proportion with the rest of the car and it is to toyota celica.

I don't mean to be horrible and mean and i know it does seem like it i am just expressing my views from a design stand point i hope you take these on board.but as i said there is nothing wrong with modeling itself its the design thats all.
