What metering mode were you using?

Can you please upload the images with EXIF intact - any size will do for these purposes.

With the OP's original images (having downloaded them), I can plainly see where the exposure has been biased by the metering mode used - matrix mode in all cases. The camera merely did what it was instructed to do ... Hence the very ordinary results.
The camera was told to do the wrong thing, and did it ...

I kept asking what metering mode was being used and got nowhere.

The plug on flash only has a guide number of 5 @ 100 ISO and using 1/200 s shutter speed this is only going to amplify his problems. The poster seems to think shutter speed will have no bearing, of cause it will.

The flash duration is so short that the shutterspeed doesn't matter for the exposure due to the flash. The shutterspeed only control the ambient light. So it is important for mixed light situation like fill flash or slow synch flash. But where there is virtually no ambient light or if you have set your flash to be way more powerful than the ambient light, what controls exposure is the flash power (which you can either set manually to between 1/1 and 1/64 or let the camera/flash combo guess it) plus the aperture, iso etc. but not the shutterspeed. This is correct.
