ah, but it doesn't matter how good it looks. 
Since you aren't making an anime ^^...it's all for
fun.  

If you did your drawings on notebook paper, you
can always use tracing paper and trace it...or do
what I do.  I handpaint the lines.  Even though at
times, it may get wobbly...there is something to
be said about handpainted lines (certain charm
^^).  

One thing though...it *does* take a *lot* of time
to do the painting, not to mention patience. 
That's why I think it's fair for someone to charge
$40 or something like that on a fancel.  One fan
cel easily takes hours (easily 2) depending on the
shadding.  

If you want, you can email me your scanned image
and I can give you a rough estimate about how long
it may take you.  If you have a lot of sketches,
you may want to start with an easier one (less
detail and less shading).

I think it would be nice to have an image to hang
on the wall of characters you enjoy (when you
can't buy -- be it you can't find or can't afford
-- the actual production cel)...

joyka.
