Nice image, good colours and great composition
I'm just a beginner when it comes to NB processing but I'd try and shrink the stars in the SII image a bit to reduce the red halo and maybe a little bit of deconvolution on all channels to sharpen up some of the details (I use Startools for this sort of stuff but I'm sure there are plenty of other options).
Looks to me like great data, maybe there's more to be had from it
