Your style is definitely one that benefits from the entire black and white inking than a full blown colouring style. From what I've seen, a full splash page might be more helpful, as the cutoff in the center seems to mis-align. The lines could be a bit smoother and thicker, but it definitely yields potential. There is a spontaneity and action-oriented feeling very much visible throughout the piece, and it fits it well.

Specifically in regards to the colouring, it seems to be a mix of two different main styles - one is the semi-realistic 'hotoshop-effect' style colouring, as visible within in the top left corner of your work, and the other is the regular cartoonist colouring visible in your characters. I would suggest keeping the colouring uniform, as colouring within a comic can lead to some level of confusion for the readers and a slight twinge of unprofessionalism. However, overall, it is definitely a very vibrant and eye-catching piece of work, and if you work on the strengths (the action, the detail and the vibrancy) you will definitely come to something fantastic in the future.
