Okay I think there is one under Clamp Campus 
Detectives in Anime Gambit. There's also one in 
Animanga under Clamp in Wonderland of Hikaru. I 
think you also missed a cel of Subaru that was up 
there a couple of months ago. It was from the 
sequence where he's throwing his wards. Oh and 
there's one of Ashura (RG Veda) up in Anime Link. 
(Most of these websites can be found in cels.org 
in the keep track page.) 

If you're feeling generous, post or email me 
scans of the cels you've got from the music 
video.
