its blue... Way to blue, but that really depends on locations ( i've had some really nasty experiences with styles at different locations in the world), so the Blue might be the thing :]
The ones i think best of is 02 and 04 but i really hate that blue dot in center, sry mahmoudnahmad
The rest get me thinking of techno graphic from the 90's
I like the shapes in 09 but the sharp blue color really ticks me off. maybe try and combine shapes with 02.
allso the drop down shadow of mubasher, why's that, it seems to far away and does not fit the shadows in the rest of the pictures.
looke to me you need to go though the design one or two iterations.
Try lower the blue color or remove it completly make it more gray/blueish. and remove the dropdown shadow of the mubasher.
maybe another one or add the £$ etc. symbols to the current posters.
/cheers mate, hope you can use it for anything.
