sure, there are a lot of beautiful photogrphs posted on this website in these threads
but i'd like to see something completely different than what is in your comfort zone.

you like photographing rocks and trees? how about uploading a portrait?
you like photographing nudes? how about an architectural photograph
still lives? how about an a abstract ..
you like portraits? how about a landscape ...

you know, something that stretches you, was difficult for you to do, and maybe, you'll do it again.
