Yeah...OK, my First Comic (Manga in SC Form) Sucked, but with Good Practice you can have Great Comics like Matt Silver's, Decepticon's and many others. Its not a bad start, but you need to Check Over Puntuation, also Don't try to cram everything in a short speech Bubble, just make the Bubble bigger. apart from that, its an OK Start.
By the way, the 3rd Panel is a bit Random, and i can't make much sense of it!
