hm.. I would suggest to have an hyperfixation!! It really helps to light up the spirit and just do something out of pleasure :) but other than that I would highly recommend just analysing in real life. just look around yourself time to time, and try to memorize the way objects look, how people stand, the folds, the lighting. I practice it a lot when I'm going out :) hope it helps! and for apps I use CSP only!
