I hope you are not holding your breath Jose! It looks like it, though. Because I don't see any bubbles, and those cheeks are pretty puffy.
Remember Rule #1 (by Jacques Cousteau, the OEM):
"Never Hold Your Breath While Using It!"
It also looks like you lost your snorkel somewhere, since you are in the open water, apparently. You should always have a snorkel with you when diving in the open water, because if you get separated from the boat, or you need to make a rough-beach entry, and your tank is empty, a snorkel will be your only salvation. Caves are different, but you don't look like you are properly geared up for a cave either (no cave lights).
I hold my breath a lot underwater, but I use my diaphragm to keep my lungs expanded and keep my glottis open at all times. It works great for me to increase buoyancy when I need to ascend slightly or stay off the bottom. My cheeks look puffy because I'm a fat guy. As far as the snorkel, I quickly realized that they're useless and serve only to get in my way, so I started leaving it in the dive bag on the boat. I know how to swim on my back on the surface, and I'm not freaked out by big waves hitting me in the face while doing so. It's quite easy to simply hold your breath for a second just before the wave hits you. Thank you, however, for your concern.
