askohen -- the two direct flash photos show more glare on the subject's face, and a harsh shadow under the chin, as compared to the bounce photo.
the color cast with bounce flash is perhaps due to faint tinting in the paint in the ceiling. It may look white to your eye but be off by enough to throw out the color balance. I generally shoot bounce flash in RAW. Also, when using flash for fill, it's only color balanced for sunlight. The colors will mismatch on cloudy days, in shade, and in indoors lighting.
