Advice on Stepfiles

[poe15]

I'm making some stepfiles(and hopefully eventually making a pack, touhou based) for stepmania. I would like some advice on my current songs that I have made(or half made)if you fellows would be so kind as to give it. Gpop pointed me in your direction as a viable KB chart source so the idea seemed appealing. Would y'all be kind enough to give advice, criticism on my charts? Attachment included.

Addendum: Beyond the Core is more or less complete, as is Judgement Star. Jeux Interdits has hard complete and a tad of expert complete, and Hardstyle Colony has normal complete with some of hard complete. Naki Oujo no Tame no SEPTETTE has medium complete. All difficulties are done from the ground up(easy onwards).

Since these are keyboard charts, one of my main worries by this point is whether or not I have hard enough difficulties for the more advanced players. I would like advice to this end if possible. if so, I may add a Lunatic difficulty to some of my songs.

You can consider this an introduction to my pack, if you like. It shall be poe's touhou keyboard pack, most likely.
