Hey, so I haven't spoken about the art direction for the app yet, and this would be the best time share this info (since I wouldn't want to be talking about it after showing screens :-P ).
I've decided to go for a cartoon-y art direction, with outlines to finish off the look. One reason for this direction is that I realized that this type of direction works really well with iOS/mobile devices and the art just pops with the resolution of the iDevices. Plus with this direction, I don't need gritty details, just make it simple and clean so I can be able to push more things on the device other than art. This works out really well. The art direction will be unveiled soon, stay 'tooned'! ;-)
