(Had way too much fun with those alternate texture names..)
One of the first models I made for my current year project was the "Roller-Rover" a militarized lunar rover designed to be a low poly APC in a spacey sci-fy themed RTS - I'm quite happy with it although since it was one of the earlier models I made, it has some primitive elements that I'd love to go back and fix!
THINGS ID FIX
Spiini-Gun: I'd definitely add some more detail to the Spinni-Gun somehow, I think it looks too basic and featureless as it is, maybe go all in with a bullet-links or ammo-boxes adorned on either side (or both!)
Rail-Guns: I'm personally SUPER turned off on the front mounted Rail-guns, I think they're a bit ugly, un-refined and frankly impractical - this thing is meant to traverse lunar terrain after all, so one high jump or bump and those Rail-guns are Rail *Gones!*
Rear: I Would overhaul the rear to add a drop-down ramp or door to make it a proper APC and give a realistic and cool functionality that way!
UV's: Lastly, On the issue of textures I'd need to fix the UV as they kinda broke around the front, I wanted some more details there but it's serviceable.
SUMMARY: Quite a special model to my heart as it inspired a lot of the vehicles to come in the college project, it was the main inspiration for continuing onto the DRAGON-BEAR And I used a similar methods to develop the Fan-blades on the KESTREL So without this model I'd likely still be messing around with those or maybe not even have been inspired enough to make them! The ROLLER-ROVER Was an energizing model to make and I'm very pleased with it!
