I'm currently designing my first iPhone application, and I've decided to go with a UI using the default UIKit controls, but customized with my own colors and textures.
One area where I'm having trouble making a decision is whether or not to use a typeface different from the default Helvetica Neue in the navigation bar. My instinct at first would be to leave the default, but I've seen several apps with different typefaces that pull off the effect very well (namely: Camera+ and Everyday). Here's where I currently am in my Photoshop comp:
What do you think of this, from a User Experience standpoint? Would it be alienating for users of this app, or would it add to the overall design feeling of the app (I'm going for luxurious but easy to use)?
