I must say, for gimp, this is impressive shading and an overall impressive image.
It appears your posts have been merged for you... I believe there is some caveat about only deleting the last post in a thread, so it may be impossible to delete your posts otherwise. I confess, we don't get a lot of delete-worthy posts (thankfully) and those we do, such as these, are understandable mistakes. In any case, I don't get a lot of opportunities to "moderate" things...
