One of those people which one of us hate? ^_~

There's nothing wrong with saying, "This is what 
I want, don't change anything!" It's much easier 
to do it that way, because both people have the 
same idea of what the finished image is supposed 
to look like. If someone's going to commission an 
artist, it's their call what they want to see. 
More often than not, though, what they want to 
see usually happens to be a moment that occurred 
somewhere in production, rather than a moment 
built totally from scratch. And the ones who do 
request images-from-scratch have usually worked 
with a fancel painter before... and have already 
requested a few "Copy these" and are ready to 
move on to something different. ;o)
