Well first things first, i like your thumbnail / display picture though i didnt like the banner as much, have you tried linking your instagram, twitter and such to the actual banner so people can just click the little icon on the bottom corner? it just looks a little cleaner. though if youre insistent on having the socialmedia names on your banner perhaps change the colour a little because the black doesn't stand out as much. your channel trailer is quite epic and i did like your new mic very much as it was quite clear but in saying that due to the fact that i have never watched arrow couldnt connect to anything there D:< soooo im a bit useless at this point but i did appreciate the insertion of images of the characters that you were talking about because it gave me a tiny bit of context XD
Anyway :3 i hope something in here helps you out a little ^^ and im very pleased to meet you
