That tank is hideous, the up/down sprites for obvious reasons... But the left and right aren't so great either... Aside from being a not-so-attractive drawing that doesn't look anything like a tank...

-The texture slapped on top of the main body on both left and right is very linear, and doesn't slope down with the tank itself.

-The perspective on the tires don't match the vehicle body itself. They have no depth.

-The left and right are exactly the same except flipped horizontally. It would've worked if the "tank" was completely symmetrical, but it's not. Look at all of those things in the black ellipse on the top...

-On the up/down sprites there's a bit of grey on each end of the vehicule showing some "Bumper" but you can see that on the left/right sprites, the bumper is pretty much flush with the whole body... So you wouldn't see that much bumper (if any) from top down.

There are a few more little things wrong I've noticed, and they all add up. But first, if you don't plan on making it look like a tank... Fix up what you have.

Here's my crappy visual aid. I hope what I've said, along with this will make sense.
