i made this lamborghini in cycles, and render time was just 4 mins ^^ Every critique is welcome! (and sory my bad english…) 
Quite nice modeling! Maybe you could have added the Lamborghini label on the bonnet. And the seats seem to be much too near to the doors (I mean where is the driver supposed to put his left arm for example?)
The lighting could be a bit brighter. And what is this orange-yellowish glare in the middle of the picture? My first thought was that it’s a reflection of the orange seat on the windscreen, but this glare is even outside the car…
edit: And everything seems to be out of focus somehow.
Nice modeling. Unfortunately the whole picture looks blurred. Also, if there are windows, it’s almost impossible to tell there are. This could look great with a couple adjustments
It looks nothing like a Gallardo… its closer to a Diablo than a Gallardo. you needed to spend more time on modeling, because this feels extremely rushed. Car modeling is really all about realism so you need to be spot on or car nuts like yours truly will spot when you are off…With this car it was a bit too easy to spot where you were off
