I agree that the hatch should probably not be white, but other than that I think you've got a very nice looking model. I'm a big fan of Tamiya's 1/48 scale kits, even if they do need the odd bit of PE to really make them pop.
A note on your photography- your images appear to be a bit underexposed. A fair amount of detail is being lost in shadow. This is probably caused by your camera attempting to balance the very dark subject with your white background. Don't know what sort of camera you have but if you can manually change the settings see if you can add a third or a half stop to what the meter is telling you. If you have any sort of editing software, you could also adjust the exposure there, although such things are best done in camera if possible.
A minor quibble, and I just want to make sure that such excellent work is being shown off in the best way possible.
