New Loading Screen Background mysteries and wonders

Hi guys, I think the new background during the loading screen is a great thing. Makes it more interesting and less "dull loading screen that feels out of the game". Now, playing several games with my mate (mostly URF btw) lately, we kind of found out weird / crazy things with the art itself and the champions art. I mean, how they live together and fit so well as a whole.

So one day I literally thought one of the champion's image background was transparent, letting us see the main green background behind the character. Then now we seem to see how well some champions and details fit with this. Some branches, colors, forms seem like extensions of each other. It's impressive. Like an arm or a knee exactly fitting the form of a tree behind. Like the color / background view of one champion fitting the main background. I don't know and hope you understand what I mean ! Here's a little example that I took http://apollo-na-uploads.s3.amazonaws.com/1428717377670/Captured%E2%80%99e%CC%81cran2015-04-11a%CC%8002.20.55.jpg Take a look at my attachments, they are better

Our simple guess is / would be that Riot have awesome art guidelines for colors, poses, lines, and harmony rules, with convergence lines and all... That makes it all so fitting together, with all kind of matching possibilities like this.

Now I would like to know if you feel the same or have already witnessed some kind of sorcery like this. Or if you have any insights on the topic
