overall, i feel like the ones with a bit more quirkiness are more you and match your personality. the beardy shots are rather heroic and mighty, but i reckon you'd have to be a bit taller for those roles.
some of them do, in some you come across as slightly too attractive and warm to be eccentric or quirky or uptight enough. headshot 6 makes you look like a serial killer.
same as above. for me, it's all about the beard.
yes, but i think you look better with a beard; it makes you look your age.
1, 3, 5, and 6 are better if you need something specific for a casting. 5 is good for more pensive, serious roles, and 1 is good for a friendly, quirky guy. 6 also does that, but i find 1 to be a stronger photo. 3 makes you look a bit shady (in a good way, like a bond villain, not a pedophile).
i think each one matches a different casting. i like 3 for 'hard man' /villain casting. 4 is my favourite as i think it looks most like you.
number one, yes. it's truthful and still has a sense of the brackets you're aiming for.
