that's not exactly constructive criticism, anywho:
I believe you call the firing points 'muzzlepoint' but that's for weapons, there is a thread by darkstar and one by demian that can help you:

as for the model, the feet are ok and same goes with the turrets and bottum of the body, but the body and the area which fits the drivers/pilots should have some work, perhaps you could seperate them and add a bevel modifier (however the results could range from good to stuff, I don't really know). I don't know how to say this but in the body, it sloops up then down, you probably already have something similar to this, but I found a decent referance image (click for max res)
Note: the feet are suprisingly quite small width wise, i'd suggest scaling them down on that axis actually.
this is rarely said for blockland models but I personally think it looks to un-detailed considering the size of it. However it's your model so you can do what you want with it
