The detail in the planet of the Tenchi space BG 
is just amazing.  Seems like almost too much 
effort for a Tenchi Universe BG.

The DBZ movie BG is just, well, unusual.  I just 
wish it wasn't stuck to the cel.  [In fact, it's 
the only cel I have that's stuck to the BG.]

The GundamW BG for my Epyon cel is at the url 
above.  It's a fitting somber book cel BG that 
really adds to the fallen Gundam.
