Focal lengths and different view points

This one I really struggled with I understand the principle and what I needed to achieve but it just seemed that no matter how many times I tried to do the set it went wrong, these two are the best of a bad job, I have decieded to move on now i hope that is ok but I was getting so dishartented I felt like giving up which obviously was not what I really wanted.

What did I notice as differences between the two shots?

I noticed that the shot done at 18mm made the car look longer in particular the bonnet, the one done at 200mm made the car look shorter, the 18mm shot looks more realistic although you do get the impression that you are looking almost looking down on it  whilst the 200 mm it almost feels like you are standing looking level with it.

As i said I difficult project for me to complete and one that has kind of held me up a bit as I want to complete the projects in order, although I have gone on to prepare for some of the other projects.
