Clouds in the Sky: "Test Track: Tron" Reimagined

Test Track: Tron
So in the last couple of weeks, before Disney released the very "Tron'ish" looking renderings for Test Track's refurb, I decided to create some renderings of my own about what I imagined a Tron car for Test Track might look like. I have recently begun to dabble into the world of 3D modeling so forgive me as it is no-where near a professional work, and I am using open source tools for modeling and subsequently rendering the models (which is fairly slow).

Anyways without further ado, I give you a little glimpse into the current work in progress that is my model.
Front View:

It was partially modeled off of Mercede's very Tron like concept sports car that can be seen here. I want to continue working with it and round off some of the sides and such like I did on the back...but I figured I better share what I had because apparently Disney is actually doing a Tron refurb, and they might release something that will make mine obsolete! The interior of the vehicle also needs to be detailed with the standard 6 seats, and the display screen. As well as the hood and headlights are not right. And I still need to redo the sides maybe to make it more realistic for loading. But it's a start and I thought I would get some feedback.
Back View:

There will be more to come, let me know what you think!! I want to get into modeling a bit and maybe start doing some Disney concepts for my ideas. It's been very cool to see a few of my ideas come to life rather than just in descriptions!
