I assume the textures are an early WIP? Judging by the noise's resolution, I think the textures might be a bit too high res for Minecraft. I'm also feeling mixed about the implementations of curves and round shapes in a game of Minecraft. Blocky shapes are like a part of the franchise's charm.
I must also agree the high-gain antenna is a bit distracting. Although, since the dish on the real moon rovers where made of a mesh you could see through, then perhaps it's just a texture work yet to be implemented?
Interesting. IMO the other one seemed too bland, but he added more details to this one that made it sweet. Well, excluding the wheels since they are not Minecraftey, but hey, wheels can't ruin an entire model, right? ........right, guys?
Well, the 'minecraftey' wheels I speak of are round(ish) wheels, but composed of several small blocks. Because a circle CAN exist in Minecraft, it just needs to be made of several blocks, in the same way that a circle can be illustrated by a polygon with 1000 sides.
