If you mean TRACE the sketch exactly as it is, 
yessir, I would have a problem. If you 
mean "copy" as in, "Boy, I'm inspired to draw one 
of my own like that!" I'd said, "Thank you!" ^.~

Seriously, thank you for the compliment! ^^; Oh, 
and even though you were joking, I WOULD like to 
point out that you DID *ASK FIRST* and that's how 
it should be! I appreciate those you make an 
effort to be polite (even in jest, egads! ^.~)

Thanks for reading this,
