* 1. The character drawings look "unstable" - The proportions look strange as do the angles. If this is deliberate I don't think it works - You should consider how angles work and what looks natural. Try to study the human anatomy in order to make movements look more natural. Also try to develop your sense of perspective so that aerial views, etc. look realistic.
* 2. The anime style that you use seems clichéd and the lack of color in the mouths just looks funny. You can use Japanese animation influences and still make a unique and lively style. The style you are using now is stiff, lifeless, and unclear. We need to know what is going on in the comic.
* 3. It seems like some comic strips are meant to be read right-to-left. That should not be the case; whenever writing a comic originally written in English it should go left-to-right - that is how the English language works. The actual Japanese manga can get away with being right-to-left because they were originally written in Japanese. Notice how the "American manga" sold in stores goes left-to-right...
* 4. If you are going to use Japanese names it is usually best to research the actual names - pick a name, formed with kanji, that you feel represents the character. You may need for someone who knows Japanese and is familiar with Japanese naming to help you with this.
* 5. Get a comic-appropriate font from Blambot: http://www.blambot.com/ - Comic Sans is not a good font for comics.
* 6. If you want to use a greyscale, get some shading in there. it will enhance the comic and add to the expression.
* 7. Work on the dialog and try to not make the characters too outlandish - If you are going to have a girl yell "But I'm different! I have BOOBIES!", you need to have other people rightfully call her a psycho weirdo and shun her. If you want her to be treated normally, have her act like a regular human being in Western society.
* 8. The layouts are not neat. The presentation is not neat.
I'll see if I have any more comments to say...
