I have a fairly poor eye for designs that I implement myself - I fall in love with features, and the screens of my iPhone apps slowly get very crowded. Also, after working on an interface for a very long time, it is hard for me to step back and look at it as a first time user would. As such, it's very helpful to get real users to comment on the screen, and professional UX person's advice would be priceless.
My question is this - let's say I have a screen that I want to show to ux.stackexchange. Is it acceptable to ask for "Does this screen look busy?" or "How can I streamline this interface?" questions, or should I focus on a specific part of an interface that I would like to receive feedback on, such as "How to use gradients in a user-friendly way?", and then use my screen as a starting point for the question.
Your feedback is appreciated!
