I really like your colors and your font and cleanliness of your design, but I'm not getting the molecular structures. Maybe if you can change that icon to represent something about air this will really be nice.
I liked your colors from before better with the molecular thingy. The new icon looks like a recycle symbol and I want to stay away from that. Maybe try again with the icon?
Yeah...i like the blue and orange...can we try the Doctors in a bolder font on the the one like #23 and again, if you can think of a bold icon using those three colors like the molecules...that might be really nice.
