A little soft on the subs I think. I found with the RC's you need to check focus fairly often. Usually every 2-3 subs you will need to go back to the focus star and ensure focus is sharp. I am at present using a Bahtinov mask to focus. When using that I magnify the images to 200% and get the focus as close as I can to perfect.

Other things you might want to check is collimation with the camera in the telescope. Place a star in the center of the image and defocus that. If you have good collimation it should present as concentric circles. Al's collimation aid will help.

That said, you have made a good start and I look forward to more of your images.
