I was mostly just being too conservative, I think it's because I wasn't sure of how much slo-mo I had in the heat of the moment, maybe you put the health and slo-mo meters around the crosshair to make it easier to see.
Another gripe I have with the UI is how the ammo count distracts me when I'm not looking directly at the crosshair, I think it should be another color and not as bright as the crosshair.
