Shawl Progress (a.k.a. Knitting Aliens)

I've finished with chart 4 of the Hidcote Garden Shawl pattern. During the massive boredom of the purling back ever increasing rows, I am starting to see things in the back side of the shawl.

I know the front side is supposed to look like a field of flowers, but I'm thinking that the back side in it's pre-blocked state looks rather more like a sea of Alien heads.
