Thanks, guys.
I thought about highlighting it but I was afraid I might over-do it and have to start over. If I had started the left side with a greyish white, i could have tried some brighter white highlights but my starting white was too white to try that, i thought i thought if i highlighted the blue side very much then it would look unbalanced next to the plain white. I also wasn't sure how to highlight up to the blue/white demarcation line without making it look funny. I also had a Shadowhawk going as a backup. I tried drybrushing it with GW Ice Blue but that was too greenish. But at least I finished something for a change.
