You've posted the wrong base....
There is more holden ssv than there is of the base - only the front arch light and bonnet remain, and you've made no attempt to keep the rest of the original lines of the car elsewhere,
This is kind of dissapointing really

Because it's a cool concept, especially with that rangerover kit at the front. You need to try and put more effort into keeping original shapes and lining up body lines, then your chops will work a lot better
However, on a positive note, the wheels and backdrop seem to fit well, and the blue colour is really cool

Just take note of the advice I gave above
