Ohhh I love utes. I like the ideas you had too. It would look so much better if the rear was longer. Also the shadow under the car is wrong, next time select the area you want to do as a shadow, right now if you look closely, you can see a black area on the left of the bumper, that shouldn't be there. The headlights could use some highlights too.
But still, I like the idea that you had, just keep working and practising
