Serious lack of originality, plus copy-pasta via tracing existing artwork of widely available, mass-produced Shounen junk + some other manga that I forgot what the name is with pretty boys and touching balls. I don't see any bit of talent in copying the drawings of someone else's hardwork.

Needs to be purified with fire, urgently. That friend of yours needs to come up with his own original idea. I recommend:
1. Work for Gempak.
2. Churn out simple, haphazardly done comic with half-baked artwork and unoriginal idea.
3. Do it 3 times a month.
4. ????
5. PROFIT!!!!
