I did this concept thinking in use it for make some 3d model for a videogame portfolio.
I use a lot of sources like the APC tank of Alien II, the vehicles of AKIRA film, and others vehicles for personal transport. Some of GITS and Akira toriyama Draws to...
I tried to do some old aspect, like Mad Max vehicles, or this kind of esthetic.
I didnt wanted to do any realistic background but I didnt wanted nothing like flat colour, or degradation... so i did something like ground texture.
I hope you will like it.
Best regards
