We like the current design in our attachments for the navigation on top. Also please try to use a more dark/black theme with colors that pop like at blitzds.com.
1. Home Page (Landing Page) - this page highlights what our service is and the goal is to encourage users to register. The email field on our sample page will land them into the registration flow. Also we are thinking of having giveaways, so something to highlight the weekly/monthly prizes would be good on this page.
2. Profile Page - user profile page to allow uploading images, show brief image gallery of the current user's photos, some profile info (name, etc.), badges, following/followers, email invitation box, category status box (stars) for things uploaded already (T-Shirt, Shirt, Hat, etc. see screenshot). The "my rank" at top should be updated with better stars or other concept if you can think of something better. Also the badges section can be redone to something bigger (so less per row).
3. Browse Page - public image gallery browse page for every user to view all fashion images uploaded.
