I thought it looked pretty good.  
As an artist I can tell you most profesional 
illustrators tape their edges. Also, the edges of 
the paper (especially on the left) look rough 
like good water color stock.  Most prints, glycee 
or otherwise, even if printed on watercolor stock 
don't have natural edges. I have seen some with 
rougher edges but they were extremely expensive 
small edition stuff.  There is also more white 
space on the left side than on the right I would 
think if it were printed they would be even. It 
definatly couldn't hurt to ask for a better scan 
though.
