Hi Wendy!
That's an incredible cel!  ^_^  

I've gone with smaller thumbnails on my own site 
for faster loading time, so I completely agree 
with you on this issue.  But yeah, that thumbnail 
is pretty tiny.  I would probably make it a 
little bit bigger.  If it's hard to see with my 
screen resolution, I can only imagine what it's 
going to look like on a 1024x768!

Just my humble two cents!  Ja!
