Thanks for all the feedback.

Just as an update: I got a new haircut and have started revamping the wardrobe.

I also retook the wine picture. Do you think this is along the right lines now?

Good points, thanks. Will retake

Thanks. Haha looking nerdy comes with the territory of quantum physics research, but I'll work on it for future pics

Great, thanks for the advice. I'll get a new haircut and see if I can put together some better outfits, and then take some new photos

Thanks for the advice. I'll get a hair new cut this week.

And order some new stuff for my wardrobe, try to keep it simple with well fitting jeans/khakis and top/shirts.

My eye sight isn't that bad so I could ditch the glasses for photos

Good point, I'll bear that in mind when taking some new photos
