WOW, It's awesome to see how much big this section has grown into,

Well I didn't want to add more weight onto it, So I am not in rush for the logo.
I am creating an app for Windows Phone (looking forward to submit it soon). So, I would need some help to design the logo for the app.

I have a picture in my mind but cannot get it to the screen. But you guys can come up with your own design ideas.
This is the idea,
1. Transparent Background (Important, for transparent Windows Phone Tiles).
2. Sizes, I would like the logo only no words etc. in dimensions 100 x 100, 691 x 336, 336 x 336,  159 x 159, 134 x 202, 71 x 110. The log should be centered. And again transparent on the background. (Important)
3. I had thought of a design in my mind with a boy's face (sort of, Like Greg in Diary of a Wimpy Kid). And I would like to have weather references in the face. (Well like Eyes with a Sun's picture).
    And this is totally your own will, I will accept any design.

4. The logo entirely should be white. (Important, This is needed a lot to go with the Windows Phone Theme).

Well I know that's a lot of stuff to follow but these all are really important (Well, Some of them).

And Since You guys helped me with the WeatherBoy Project (I know it is not listed in my webpage, but it will soon.) I will show some sneak peak of images.














And don't think I am an awesome UI Designer with these pictures (Well, Thanks if you think so!!! ) these all are the power of XAML.

I am happy (if there is a C# section, or a general section to post misc. tutorials) to teach you guys Windows Phone tutorial if you want.

Thank You,

EDIT : And by the way, You can also suggest any UI Improvements.
