Jan, I've been a fan of your work for a long time. I've collected many of your repaints including your most recent on the B-26. Great work!!
So having said that ...in my opinion the last shot looks very impressive. I think the low cloud base gives you the feeling that the aircraft is at a high altitude airfield. Everything looks good aircraft wise but I think the vehicles in the background are out of scale. They're too small. I know this isn't your doing, it's one of the quirks of FSX.
An Aircraft Mechanic only needs two tools, Duct Tape and WD40.
If it moves and it's not supposed to - use the Duct Tape.
If it doesn't move and it's supposed to - use the WD40.
