Yes, it's the cracked willow - one of the best trees in the collection.
Indeed, the surfacing is sub standard, although it was interesting to do: meaning I learned something about masking while making it. Maybe I can re-use that knowlede in a future image, in which I will invest more time than this. I haven't had the patience in this one, as it took so long to figure out the clouds, that virtually no patience was left or the terrain :-D
Cheers,
