First time diy

Bought our first house last year and gutted the upstairs to change the layout. After lots of additional projects and unplanned repairs (house is over 100 years old and previous owners were hacks) I finally was able to hang drywall in what will now be the master bedroom. This is the first time I’ve taken anything on other than doing a patch or replacing a few sheets behind a tub surround. I know it’s not perfect and the windows will be replaced sometime next year so I didn’t finesse around them but is there anything that looks like it will give me issues when moving forward with tape and mud or anything I could do differently for the next room and the landing area?
