This thread is linked in the main thread by theymos, as the location for additional discussion... why would the OP lock it?? A subject change, possibly, but it's really not that confusing.
Sorry, I didn't know that it is linked to the main thread. Confusing because of the Subject name. Even I was confused while posting my art. I opened this thread to post my art and realised that it is not the main thread. A subject change would probably help!
