I folded the pig some time ago when it was published in the origami USA convention book 2010, but I was not happy with the result so I didn't show it. I really like your models though and any diagram you make will be appreciated.
I finished this diagram in 2008 and contribute a piece to OUSA for 2009 USA convention book , but I have no any information about if this diagram can be adopt until 2010. If they let me konw they want to use this diagram early, I don't poublic it.
The diagram is in the 2010 OUSA convention collection. It has the same information that you said: the diagram was made in 2008. It is on page 132-234. The model looks very nice, but I think OUSA ranked it a little low: low intermediate!!!
