For this design, I wanted to mesh both the Tumbler's and Tim Burton's first Batmobile's attributes as clean as I could without making it seem too obvious that it's either. The size is pretty big, just picture a wheel the size of half to 3/4 of your parents. The windshield, long nose, and jet engine was definitely what I wanted to keep. I transformed the wingtips as the taillights, inspired from the 60's Batmobile's red lining. There are elements that are not pictured here (i.e. moving parts, weapons, etc.). I'm anxious to start 3D modeling it, but if you have some suggestions before I start just let me know!
I'll post further pictures when I start 3D modeling it. I hope you like it!
