Your image has good detail, dust lanes are there. Also the visual double star on the edge of the galaxy are separated, most M83 images don't show this level of detail.

I see you used 300 sec subs, have you thought about using shorter subs?

I watched presentation on youtube by Dr Robin Glover the author of SharpCaps. Talks about optimum sub times for different Bortle zones. Recommends very short sub times in Bortle 9 to get lots of subs to make it easier for stacking to improve the signal to noise ratio.
