Please not that design #22 is perfect for app icon/favicon use and facebook/twitter avatar pictures, as it is already a 1:1 square ratio and can be scaled to fit any web and social media needs with no additional cost brought on by manipulating it to fit the required square shape.
Its the most multi-purpose of the designs I uploaded for you (along with #25)
Thank you for your design, we really like the idea of the favicon and the white picket fence! Unfortunately, at our team meeting today, we had a vote and another one won out. Thank you for all your efforts!!
