I've been doing a whole lot with screenshots lately. I don't have anything to do with the artistry inherent in the game - all credit for that goes to the developers and graphic designers. So when it comes to taking beautiful screenshots, as kittenmommy pointed out, composition is the big thing. Composition can be really a hit-or-miss sort of proposition, and oftentimes it's very trial and error. If you pay attention to the bottom right and left corners of the screen where I usually hide the chat box (I can't get rid of it or make it any smaller) you'll often see that this is the third or fourth screenshot I've taken, or that this is the third or fourth time I've had a character perform an emote so I could try to catch them at the absolute perfect moment.
That being said, I spent some time last night experimenting while Astrid was farming (actual farming is shoot-yourself-in-the-head boring, so I had to occupy myself somehow). Here is the evolution of the screenshots I took from start to finish so you can see where I started and where I ended up going. The premise is Astrid (Astridd in the game because 'Astrid' was taken, but 'Astrid' is her actual meta-name) standing in a field of lily-of-the-valley blossoms in the shire, seeding and harvesting with the stars spread out overhead.

Welp, that's my study for today! Hope you found something pretty! Feel free to let me know in comments which were your favorites! Some will probably get sent in to Postcards From Middle-Earth.
