After a day of viewing it in various room lights and after a break I have decided that while I liked the blue appearence I decided the Ha (green) was not obvious enough and the Ha/OIII mix within the nebula wasn't obvious enough either.
The Ha and OIII form layers within the nebula and now these layers are more distinct and the Ha and SII have clearly mixed to make the yellows and the Ha appears to hover above the OIII in distinct patches, much happier now
