For what it's worth, as of yesterday I've cleared every game except the PC-98 games, the fighting games and PoFV on normal. -shrug-
I might move on to Hard... eventually :V
Not too bad, Nolegs the Cat! One has to start somewhere, indeed, whether easy or normal! Many of the best, for example, had to start up small, and their many great achievements they have done were not some overnight thing, it was the result of months, perhaps even years, of hard work, play, and practice. They may have even played games similar to Touhou, more-or-less, at least, in the context of the shmup format.
Don't mean to nitpick, but I couldn't help but say this, and I apologise in advance of this... Not going to consider doing Great Fairy Wars? I see that you haven't submitted anything for Great Fairy Wars, so I felt I had to ask this. Also, you could give the "Mystic" (Extra) stage bosses a try, if you haven't considered this already, which I'm certain you have. Playing for score is also a possible consideration, as well. It could also help you prepare for the harder difficulties.
Also, some "Heroic" (Hard) mode games I could consider off the bat, based off of my own experience, are Perfect Cherry Blossom, Phantasmagoria of Flower View (If you ever get to do that), and Ten Desires.
