Look at that face. :3c

No i do not think it is a bother... i think people with no artistic skill should be able to use SL as a medium to make reference sheets.. However i do not know if SL has requested people not use there stuff.. I would suggest you put it in scraps after a week or so.. and see if you can work something out for some art to be done to use a future reference.. Yes SL is nice (i have an assume looking avatar of Akyi on there) just in the end there is still detail you will never be able to express.

I think they do require permission, I totally forgot that and meant to load this into scraps but forgot that too. Hopefully one day I can actually get a drawn ref sheet so I don't have to use something like this!
