I have made few variations with the tail of the Q just like that in the font. I also made the lines thicker in the icon. The design is purely flat, i used flat colors and can also look good in a single color Please check the newest entries
#272 and #273 with the strong red and closer to the blue part. But making it close to Blue will look more like a circular logo, i extended the red part to look more like 'Q'. What do you prefer?
