Wizard Nebula in NRB with RGB Stars (and comparison of RGB-Star addition)

Finally I'm getting comfortable with NRB colours.
On this project I decided to try out all the interesting new modes of RGB stars combination with NRB.
The renditions show following methods:
- Original RGB stars
- Screen function in Pixinsight Pixelmath - combine(x,y,op_screen())
- James Lamb's new Enhanced Star Blending Method (https://www.youtube.com/watch?v=hX3LKhwqwvY&t=416s)
- Bill Blanshan’s new method for RGB-star / NRB combination (https://www.youtube.com/watch?v=nqnONWVwf-A&t=2085s) M1 -M5 show the 5 different formulas/ methods in his pixinsight formulas.

As you can tell, the results depend a lot on the background colour of the nebula in combination with the colour of the stars.
What are your thoughts on the results?

C&C welcome

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
