Maybank2U Concept Redesign

It's been a long time since i've dribbbled something. First time trying to design an iphone app.

This ia a rather simple redesign of an existing app which can be found here http://itunes.apple.com/my/app/maybank2u-malaysia/id483084286?mt=8 .

Lot's of tweaking needs to be done me thinks. Any suggestions? Here's the full preview http://dl.dropbox.com/u/5357326/maybank2u_concept.jpg
