Hey...Elves have pointy ears as their only/primary distinguishing feature, yeah? And human looking means you can pass yourself off as human, which in Dwarves and Orks is a lot more significant. I'd say you'd need a test-a DNA test.
Heh, I like observing how you guys operate.
As for the radar eyes, the general picture is that you see cyberware here and there, more signs of weapons, and most are concentrated in your area, near the booths. You're not examining anything in particular, yes?
