Pretty well done! Very simply, without unnecessary. For social network "Vkontakte" just right. Also suitable as an icon for the iPhone, iPod and for other means of communication. it is very convenient. In my opinion a bit weak technique and originality. The letter "B" might be a bit more original. For example, you can make a shadow. But this is just my opinion. I really like the top glow. Perfectly matched in color. I want to thank you for the icon. I use it as an icon for the tab on my iphone. This is my first critique. Please do not judge strictly Sincerely, Web5teR.
