I don't think I consciously pick apart writing I enjoy or am interested in in the same way you would a website or app. I tend to notice some things naturally, like how I would write about the piece, and other things I just tend to know - like whether i enjoy the writing style or not. I do find myself picking up elements from other writers I really enjoy or am reading a lot, though that's mostly not a conscious thing, either. For example, about a year ago, my writing went very Prachett-like for about a week. A few years back, when I started reading Bukowski, my poetry went from long, ode-like works to really short, free-form Bukowskian works in the space of a few days (though that one was a bit more intentional). I think it's really just what I'm interested in and enjoying that finds its way into my work.
