I must say it...this is excellent (in size, color and story)

excellent story? You mean the `Alice makes love with a guy at the hotspring' is an excellent story? I agree with the other points however.

Plus there's a plothole. Alice removed her headband on the last page, yet it's back now.

I think she remembered she's a Touhou and cannot live without her head gear while off-camera, and then put it back on...

These images look great, however. I really like it.

there's probably a time skip, and they're out of the bath now, hence the headpiece being put back on.
