Nice job! I love the colored backgrounds - this is indeed gorgeous to behold!
Every single time I see the CSS in Smash Wii U and 3DS, I am floored all over again. Sakurai and his team really did it - they brought us the ultimate, utterly-comprehensive Smash roster that includes almost every notable Nintendo, third-party, and fan-favorite character that has been widely requested throughout the series' history (Ridley being the one notable exception). I mean, it's just a legendary character lineup. No future fighting game is likely to ever have this incredible a roster ever again (save for Smash 5, and maybe not even that since they're going to have to stop making the roster even bigger at some point)... man, what a wonderful time to be a Smash fan.
I'm also utterly impressed that not only is Smash Wii U/3DS's roster the biggest in the series, it's also the most balanced roster in the series by far... or at least the most balanced one since Smash 64. Of course this game has its generally agreed-upon strongest and weakest characters, but there's no character in this game that is utterly broken or impossibly better than the rest like Fox/Falco/Marth/Sheik/Peach in Melee and Meta Knight in Brawl. The gulf between the best and the worst in Wii U/3DS is far narrower than that of any other game in the series save for maybe Smash 64, and I still can't fathom how Sakurai did it. Melee had 25 characters and Brawl had 39, and both were incredibly unbalanced... yet Wii U/3DS has 55 (so far!) and it somehow isn't, or at least isn't as much. What an accomplishment.
