I will echo what has already been said..your art style is good and this looks very promising...but...
Constructive critiscm
Aside from the obvious crotch region your starting character is very androgynous.
The tapering pointed chin on a curved jawline is the classic "manga/anime" female shape and your character already has one in the first panel.
Additionally, in terms of overall frame and body structure, the character could easily pass for a slightly stocky girl from pretty much panel #1. Remember the average woman only has 2/3 of the upper body mass of the average man and 3/4 of the lower body mass.
If youre going to keep going with a mangaesque style you might be able to make noticeable changes to the character as manga style girls allow for a bit more stylisation, but if you stay in the more realistic style or a realistic/manga fusion you really haven't allowed yourself much room to work without turning the lead into a stick figure with boobs.
That said, do what ever your vision feels is the right way to do it. If you want more examples of what I'm talking about check out the link below.
