Sensorite Gone Wrong!

When I was a child I was a Doctor Who fan (see, not much has changed) and in the fabulous book `The Making of Doctor Who` there was a photo of two Sensorites which I found oddly fascinating. I'd never seen Sensorites before and imagined they were very evil, dangerous aliens. However the book's episode guide told me that in serial code G (which I didn’t even know then was called `The Sensorites` though I might have guessed) the enemy had been a disease killing them so they were not evil. Still they looked it. These aliens were quite unlike anything I’d seen lately which were things like the Sea Devils.  Anyway at the time I was also a member of the Doctor Who Fan Club and members used to send in their drawings so I foolishly drew a picture of a Sensorite and sent it in.
