I loved this season new art style but got use to it I'll miss the old style but anyways in opinion this is my 2nd favorite season good story and the sound on this was good as well it's clear my enjoyment on this season was a 10 man the last episode made me so emotional but i was mainly happy it looks like Rias's and Issei's relationship's began to progress near the end of this season and if you saw what was after the credits it's very likely a 5th season is coming if your a big fan like me your hyped as well.
