One thing I learned from an art teacher a long time ago was to step back from your work on occasion and look at it from a distance. When we spend a lot of time close to the screen/paper/etc, we can sometimes lose our sense of scale and alignment. I use this method still to make sure that I'm on the right track with my pieces. If corrections need to be made, it helps catch them early.
It also helps with recognizing that minor mistakes are maybe not so bad. An errant brush stroke noticable at 30 cm away is usually not very noticeable at a distance.
Hopefully this helps!
