This should be entertaining...
"The first 10 people who comment on this journal will get a sketch, free. However, in return, you must offer 10 free sketches in your own journal. If you've already done 10 Free Sketches, simply link the journal entry in your comment... You still qualify."
I suppose I'll work on these this weekend and next, depending on my other workloads, so they'll all be up by next Monday I hope :)
Please don't request anything too risque *coughsamcough* but anything else goes, but realize these are sketches, not masterpieces.
