Alright, I read your comic and here's what I got.
First, good scope of scale. I like comics that dream big. You had me at Floating Island School.
Second, work on establishing characters. Some purple haired girl wants to see black hat after class? Who is she? Who is black hat, for that matter? I didn't catch their names. I haven't seen the face of most of these characters. Woof.
Also, I swear I thought Baldy was Saitama until he threw a fire-ball.
Third, Word balloons go from left to right, top to bottom in that order. Starting from the bottom left to the top right makes it look like both balloons are being spoken at once.
Finally, I really dig the anime influence on your story. Some people might turn away, but they are gaigin bakas.
Keep it up, Bra.
Oh yeah. and here's my current project.
