i-TTL doing its excellent job to balance the light even with direct flash with its head straight forward and no dome.

Not what you may want to do for a close-up portrait.

With the flash head at 60 degrees, the shadows in the previous shot fade a bit, contrast decreases.

Still a bit too hot at the top for a shot at this distance. Not recommended.

Light is much better when bouncing from the ceiling straight upwards at 90 degrees.

If you are planning to use flash, try not to forget your dome. If your flash doesn't have a dome, at the very least get a Sto-Fen Omni-Bounce for it, although there are better alternatives as you will see in following rows.
