Well done. The problems that you had are the reason I avoid the ready mixed skims, with the Easy Fill option you can make the mix wetter to allow an open time that suits the wall/size of trowel/skillz of operator. When the skim is drying you can usually spray it with water and polish it with the edge of the trowel, it takes a bit of practice though. In any case you'll arrive at the same end result.
