The porportions are right (rule of 3rds), the colors are nice and complementory, I like aircraft, it's scenic, there's action, it is relatively clean, large resolution, no extranious details.
This Pic fits whats going on right now down in Kelowna BC Canada! (Where I Live) As you all may have heard, I am surrounded by forest fires :'( Hahahaha so I thought it was very apropriate. VERY cool!
