Yeah it still needs more color, this blue thing is not working fro me, but this is still much better than the original UI! I really can't understand what they were thinking when they created this dull UI!!!
Nah, your homescreen is too busy. You have to consider the fact that WP7 tiles are animated too.
I like the big targets of WP7 because in day to day use it will be easy to hit those without too much slowing down and aiming. I thinks its one of those user experience things people may not notice until the phone is actually in their hands.
The only change I would like to see in the home screen is some transparency to the background image.
i think that the standard wp7 metro ui it already complete and doesn't need label for icon, because they are already "explicit" for the target, adding label it's a duplication of information (label + icon) and result it's an heavier ui...
i'd like having the ability to change te background color of every tile, having the possibility to set a gradient, and the main background.
i think that it's only a matter of time that wp7 is released and we become familiar with the new ui and os
