Very nice paintjob indeed. Jimmy is right about the exhausts, they should point up, rather than to the rear. You should be able to fix that, if you can carefully remove take them off. If you do, it would really improve the exhausts if you drill them out, or at least paint the top black, to give an impression of the pipe being hollow. And modelman pointed out the turret skirts, which are basically upside down. Perhaps you can carefully remove the triangular sections at the front, with the help of a sharp knife, and swapped them around and glue them back. One last thing, but now I'm really nitpicking, the driver and radio-operator hatches are reversed. The small triangular lock plate should be towards the outside edge of the hatch, not the inside.
Are you going to add the side skirts, and a commander figure?
Nice work, thanks for showing.
