Troughton - Call the Doctor W.I.P

As you already know this is the second panel of my current Dr Who work showing Patrick Troughton, the 2nd Doctor from 1966-1969. I am going to add for each new panel the Doctor's most well known enemy from that particular time period. Although my first cartoon didn't show it I have since drawn a Darlek alongside Hartnell. Here it is an early incarnation of the Doctor's second most well known foe, a Cyberman.
