Alternative images for main page

Since the original mockup has images that are bound by copyright, here are 2 alternative images for the main page that are free-to-use:

This one is not bad (still showing the difference in age and also artistically shot), although the colour is now B/W and loses that 'bright' feeling...

This image still shows interaction between two people although it doesn't fit with the caption that well... (of course captions can be changed)

It's hard to find a free-to-use and perfect replacement for the image in original mockup... Personally I quite like the first image, maybe the issue is just the colour. What do you guys think?

We can shoot a photo similar to the original one, but well, the lighting' and everything else's gotta be really good to look professional.

Anyway, this is just for main page. The image for 'members' page is another copyrighted image, so I still have to keep looking...
