PSA to those designing thematic skins
I feel as if you posted your wonderful creations close to the beginning of upcoming events, there would be a higher chance that a Rioter sees it and considers using it!
For example, I just saw a "Spooky Bard" post (http://boards.na.leagueoflegends.com/en/c/skin-champion-concepts/PMBtAYMQ-skin-spooky-bard) which I think is timed perfectly seeing as halloween/harrowing comes up in 2 months! I feel like this is also the prime time to be posting Christmas-y designs considering thats around the corner as well.
A christmas submission in February is as good as any submission, but I think it just has a higher chance of becoming an actual skin if its before the event, and not after :)
It makes me sad to see a skin post that fits into a theme that has passed recently, because unless it's used next year they wouldnt just randomly add a new skin to the line.
This isn't meant to be pessimistic to those creative people posting skins, but more of a tip I suppose for people who really want to see a skin of theirs in the game :)
