Overall I like the look of it, but I would move the side sponsons to a forward position just behind the forward side view ports. Also, the side arched bits look out of place location-wise, but I would actually consider leaving them out altogether. You might want to make the armor skirting stick out a bit from the actual wheels so as to simulate that the wheels are not bolted to them such that they have some sort of shock absorption ability. However, in the interest of making a sturdy model, put some posts connecting that skirting to the inner tank hull so as to reinforce it(might need 2 or 3 or them per side). Obviously you put them where they don't interfere with anything, so take that into account when viewing the very rough diagrams below.
