I love this comic C=!
I really like the style of colouring - with no screentones - makes the pictures look very clear.

Don't be sorry for the lack of background! I think the background is not as important in the panels with the dialog in them, because it can distract you from the characters =)! And it makes the reader appreciate the background when you actually draw it in bigger panels in other parts of the comic, with detail and everything.
