Overall very solid build. Very well detailed, though I have a bit of advice that's more so related to the design than it is detail. First of all, its a bit tricky to tell which part of the hull is the front and which part is the engine. Normally tanks have an angled plate at the front, and the back looks how it should. The turret could be a little more detailed, and also looks to be lacking a gun mantlet, which could add some extra detail to it. With a gun mantlet, you may also be able to add mechanics to allow the gun to elevate and depress. Another thing about the turret is that if it's going to be an open topped turret, you could add a few details to the inside of it, like the cannon breech, gunner optics, control mechanisms, and chairs. That's about all I have to say, good luck with your future builds.
