Yuu Watase does accept fanart/gifts, I've given 
her fanart of God Suzaku 2 years in a row (might 
do someone else this year but I like drawing 
Suzaku).  Last year people gave her dolls, 
flowers, art, year before a quilt, etc.

About cel offers, I get a lot of them and the 
majority are on cels I have no intention of 
selling.  So if I get offers on those, especially 
if marked NFS, am slow getting back.  I also lost 
a lot of email a while back when had corrupted 
mailbox file and had to restore from older backup.
