Wow! Love that rust weathering. The only "mistake" I see after a quick looksy is the masking on the side hull for the digital camo. It could've been a little sharper and not tilted. The hatch looks like you might've tried some color modulation but I still like it.
Pat yourself on the back for building an awesome model. I'm going to refer to your model whenever I do my next rust weathering.
Take care,
