Absolutely! Yeah like it's not realistic to go back through like half a novel and make a bunch of changes, most of my points were intended to be more like just things to consider as you keep developing your writing. Also at the end of the day it's your story and your voice so take and leave whatever works for you :)
Posting for the first time is always stressful (hell, I even get nervous posting comments sometimes) but I think you should definitely stick with it and keep having fun with it.
