Tidy work is all part of a dancing act, will a few key things needed to do a good job.
CLEAN tip
Leaded solder
Tweezers
Magnification. Depends on how old your eyes are, dual lense heatset is all I need
Temp control.
Too finer tip can be a curse as it won't hold enough solder.
Needle tips are hard to use for other than very fine work when there is little thermal mass.
Chisel or hoof styles seem to be the most popular.
For SMD passives, I just wet a pad with solder, hold the device in place and re-heat, then solder the other pad. Too much solder on the tip or added will leave balling like yours, a concave fillet is whats required.
If it looks ugly, get the sucker out and do a pad again.
I'd add you job looks nice and clean.
