Way too much mud on first coat and corners sorely need tape. Check out Utube videos and practice on a sample joint. The most common mistake newbies make is they apply too much compound and play with it aiming for perfection the first coat.

He dug burrows under my shed last year and now he’s reared his ugly head again. I’ve tried plugging them but to no avail he’s determined to stay. I threw firecrackers down the holes and I even shot him with a pellet gun but it didn’t do anything but kept him more alert to me. I don’t want to harm him but when animals get destructive it’s war. I’ve read also that ammonia and also applying epsom salt around the area but I’m tired of playing. I’m going to HD and some hardware cloth and bury it about a foot around the perimeter after I treat the area so he’s not trapped after I do it. Thanks for reply

I built my shed about the same dimensions 15 yrs ago. I 2x4 preframed the base with inside joists 16”” on center with blocking in between. I set the base on concrete pavers on the perimeter and some on the interior for additional support with 4-6” gravel tamped under each. Leveling pavers and setting base took some time to get it right bc my yard was sloped but not too bad. Still standing and solid. Live in MD
