Awesome pics Liddo-kun.
It's a bit late, so I only have time to go through your report on the first day, I'll look through day two tomorrow.
Great cosplays, my favorites are: Alyssa's Fear Kubrick, Arnauld and Mich's Chuunibyou, Theta-chan's Kurousagi, Theresa's maid cosplay, Umeko-emi's Umi Sonoda, Vaynard's OC (I think it's a variation of Tohsaka Rin), Rielle's Irine, Kim's Cure Rhythm, Mika Mikachuu's Annie in Wonderland, Mia Aihara's Kojima Haruna, Meliza's Eli, Reia's Ersilia, Meowchii's Sakuya Izayoi.
On a side note:
Viola is from the game Soul Calibur V.
Which is unfortunately the worst game in the series, but Viola is one of the few positive points to the game, and interestingly enough is one of the only characters I like from it.
[Edit]
Responding to day two, same reaction as day one, awesome.
A lot of great cosplays, the ones that stood out most to me were: Lianne's Chii, Mina Kim's Gothic Annie.
Now I have to admit, that I personally do not like Pokemon (I have my reasons), but Marie's costume is so adorable and full of pure awesomeness, that I will make an exception here. ^_^
