Sometimes you just need to quit eyeballing works that are several levels higher than yours, let loose and don't use critical mindset for once-- like a child, in order to connect with that different type of flow: It is to tap in more to your right-side of brain, which is non-critical & free flowing. Instead of the constant comparing, grandiose visions in your mind, see/discover the beauty of simple arts/storytellings. Eyeballing cartoons, animes, comics, arts (which you enjoy) with similar level like yours. (Yes there's plentiful out there)
For me I don't look at technically/detailed beautiful art for no reason because it's just not fun to me, my eyes are more on simpler arts (& cute things) I have no satisfaction drawing artworks that's over the point. (though I like my BGs a bit detailed to be on-point of looking immersive). My goal to my work is: Is it on-point? Or better: Is it effective(for me & readers)? Sometime I may go lengths to get the effect done, it happens naturally to me and I don't sweat about it. I relax a lot (I'm not the type who can work orderly everyday), and I see Improvement as a side-bonus-- not primary objective.
