NGC7635 - The Bubble Nebula in modified SHO

Following my new colour scheme I developed during processing of the Wizard Nebula (Sept. 22), I have made this Version of the Bubble Nebula, NGC 7635.
The colour mapping is based on a modified version of SHO, with Ha and S2 in the red, Ha and O3 in green and O3 in blue.
In fact I processed this data set several times, comparing different colour schemes, like classical SHO, "Adam Block's approach" on the Rosette Nebula, following the newest TAIC episode with him (https://www.youtube.com/watch?v=vRfeUWfrsKc) and this version. This mod. SHO is based on Adam Blocks approach. After having used pixelmath with a Ha-O3 modifier, I stretch with GHS and use ColorMask script to work on red, green and blue separately with the Curves process.
C&C welcome – I would love to get your input and will try some variations in the future.

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.
