Love this one.
Think some of the colors were lost in the last few stages, making the air look smoggy. Carve out some holes in that filter to allow some focal points for deeper and brighter colors to pierce through more brightly. The water and metal are reflecting very little light.
Thanks a lot!
Probably so, I think some of the colors that are touched by light need more saturation, or something along those lines. Same for water and metal, something to work on. :D
