Eastern Veil Challenge

[sandconp]

I am looking for some input on how to increase the blue(oxygen) color in my Eastern Veil image and other suggested improvements.  I already processed my image and I will provide a link below on the outcome of my processing.  I am very new to PixInsight and I am still learning.  If you do process my image, please provide the steps that you performed to improve my image. 

Here a link to my final image which I put in a JPG format:
