Yes, that third shot is a definite improvement! Terry has given you good advice.
The very idea of pointing the flash upward at 45 degrees baffles me. Flash units even have markings on them to indicate this angle, and I have yet to understand the value of this technique.
To me, 45 degree bounce is a recipe for disaster. First, the light will tend to hit the ceiling directly above the subject, and being lit from directly above is especially unflattering for older people (it doesn't look so good for younger people, either).
Secondly, at 45 degrees, the amount of light that hits the subject directly from the flash is a total crapshoot. It depends on how the flash is zoomed, the distance, and the focal length used.

Light bounces off surfaces in exactly the same way as billiard balls.
This statement calls for further discussion. Light will bounce off a mirror or other glossy surface much like billard balls. But it will bounce off a flat white surface (like a ceiling) IN EVERY DIRECTION.
This is somewhat of a generalization, but I think it's a good way to think of bounced flash: With direct flash, you're lighting whatever is in your viewfinder. With bounced flash, you're lighting THE ENTIRE ROOM. The illuminated area of the ceiling essentially becomes a large, diffuse light source.
