Nice progress Hermann! Like your camo pattern, tough one to do but you've got it matched up nice going from the hull to the turret. A filter and an oil dot wash should blend it nicely.
Regarding your silvering of the turret bin decal, did you apply a coat of future before applying the decal? If you gently prick the area with a pin or needle, then apply a bit of future you may be able to reduce the amount of silvering. Maybe soaking the decal in solvaset may lift it a little bit, don't know for sure.
The oil dot wash may cover the silvering up as well, just a guess though. Hopefully someone else will chime in if I'm off base with this.
Thanks for the progress photos. Keep at it!
