I like the italized and it would be cool if you could implement a globe of some sort - representing our worldwide capability. Or perhaps you could implemet the 1/2 star of life with a 1/2 of the globe or blend the 2 somehow so there is not too many clip art in the logo as we do still want it to be simple and identifiable.
I like the 2 color idea for simplicity as well. No more than 3. Im not sure I like the gold color.....looks bad, but modify the colors and play with them more. Remember, this logo will be going on jackets, shirts, letterhead, trucks, aircraft, equipment, everywhere....We want it to become our identity. The colors have to be rich and very attractive. i hope this helps.
Much better....perhaps you can add something suttle...we do air ambulance all over the globe. Could you add a 1/2 arrow or aircraft looking thing symbolizing an aircraft or arrow. I just want to see what that would look like. I think its great, but I also don't want it to get to busy because it may be too much for on trucks, golf shirts etc.
