I do have a couple critiques and suggestions if you would like to see more interest in your works here.
My biggest critique, almost a complaint, is that there is nothing particularly distinguishing, interesting, or unique about this format of transcription 'arrangements'. I don't mean to be insulting about it if it comes across that way but I can't put it into nicer words while retaining my sincerity. You're most certainly inspired by the wrong type of piano arrangements here -- those awful, uninteresting, unambitious 'easy mode' touhou piano arrangements that saturated the 2009 youtubes.
Why do people listen to music? For different reasons surely, but most probably listen to music to get some kind of experience out of listening. If you can't convince the listener that your music offers any substantially different experience from any of those other 'easy mode' piano arrangements on youtube, then the listener will go elsewhere.
And it doesn't all come from the music being amazing (though that helps). People like to form emotional connections to music. The problem with bad transcriptions like the 'easy mode' youtube piano touhou arrangements is that they only serve to satisfy the most basic level of curiosity of 'oh, I wonder how this piece would sound like on a piano'. These transcriptions are so babelfish levels of bad, direct machine translations that it's impossible to form any sort of emotional attachment to these mechanical renditions. The emotional attachment comes from the original piece itself, the reduced piano version only provides a satisfaction to curiosity.
To begin with, that self-satisfying attitude towards transcription is entirely wrong. These are the people that would upload GXSCC '8-bit arrangements' just to satisfy the basic curiosity of 'oh I wonder how this would sound like in chiptune form'. Again, babelfish translations with no artistic or emotional value. The original point of even doing transcriptions were so that musicians could play pieces they liked on their own instrument. Here there is an actual personal element to the process and outcome. Musicians know the ins and outs of their instruments, they know how the instrument best expresses its music, and they know the limits and characteristics of their instrument. Transcribing music is simultaneously an art of reducing the original to be playable on another instrument while also exploring the music with the characteristics and limitations of the other instrument. Even though transcriptions tend to be literal, good transcriptions have their own unique touches of personality such that you could even appreciate the personality of the musician behind the transcription. This is why you can have multiple people doing their own transcriptions of the same music and come up with very different results that are each interesting.
Now I will provide you with something better. There's this one person I found whose touhou piano arrangements fall more towards transcription than arrangement, Mitty, that I really quite like.
Here is a link to one of their videos of a piano version of the latter half of the music from DDC. Much different from those stock 'easy mode' transcriptions, no? You can hear the author's voice clearly through the multiple transcriptions they have in the same video. If you would like to gather more interest and, more importantly, grow as a musician, then I will strongly advise you against -- or even forbid you from -- ever referring to those awful stock 'easy mode' transcriptions and instead find inspiration from better sources such as that video I liked above. And this is only a starting point. Listening widely will give you much more, better ideas to use in your own arrangements.
(Oh, and as a further suggestion, I would suggest uploading actual music format files instead of midi files so that potential listeners don't have to go through the trouble of downloading the file and inserting it into some midi player application. Would you really want people to listen to the music you worked hard on with the default windows midi piano instrument sound?)
I wish you good luck.
