This first one is just my own design, although inspiration was taken from the Keaton Batmobile. There's really not a lot to say about it, especially since I updated it with the following one.
Now, this one was taken directly from the Keaton Batmobile. However, there's not much visual difference from above, just some added curves and a different cockpit. However, structurally it's been changed a lot, due to the addition of this little feature:
I do love Batman Returns.
Now, while I am happy with this MOC, it obviously doesn't have all the sleekness that made the Keaton Batmobile. I'm going to buy a few of those nifty arches from the official Batmobile, and then I'll also work on improving the back a bit.
Anyone have any further comments to add?
