Improve my profile picture

Is there anything objectively wrong with my profile picture? I plan on updating it with a new picture with higher resolution but wanted some feedback before I do. Does it look like I have a big red zit right between my eyebrows? I think I did when thus picture was taken. I'm probabaly gonna push up my glasses and trim my mustache so that it doesn't cover my lips. Are those good ideas? And while we're at it what kind of other real pictures of myself should I post in my gallery?

Hmm, I think people find picture where you're doing something you're into (Ex: Hiking) would be good. It's also a good idea to have one picture where you've shaven. Some girls are into the clean look. XD
