I agree with Olivier. Colour, detailling, weathering all appear to be on the spot and the overall appearance is very realistic. But the antennas catch the eye - and not in a pleasing way.
If you choose to replace them, I recommend not to colour them plain white. As this pic shows they seem to be more of a cream colour.

The M2 Browning looks a bit too grey and dull to me. Maybe some metal pigments to rub on will improve its metal appearance.
I am shure, that if you take care of the antennas, you will turn a good model into an excellent one.
Keep up the good work.
