Novice it's nice to see you in the CoA drawing threads. Your attempt is not bad but I will recommend you to lighten the blue background a bit. I know which source you used and that blue is very beautifull but often a little darker than original. Besides that you should smooth the wawes. Eventually kit batch some wawes from another badge
When you are drawing this badge, can I expect you will draw this beautifull heavy cruiser too
[Edit]
Oh, you certainly wrote that too. How could I oversee that
[Edit Mar 03, 2012] Excellent
I will put in a template and attach it to the other members of the british CoA's
