I'm no expert, but I'll give it a shot. Maybe it'll 'spark' a discussion featuring more experienced opinions.

The plug looks decently clean, so I'd say you're close to a good tune. The rim looks slightly fuel or oil fouled- maybe you're pushing a little oil in there at WOT, but not crazy. The tip of the strap doesn't look like it is running quite as hot as you want, but hot enough to run pretty clean. No signs of leanness or detonation.

OK, how'd I do?
