Egg shaped or not~this is a really good image. It evokes/invokes an emotional aura in its' viewing. The suggestions about re-sizing would probably have made the moon appear more "circular", but I think that is more personal taste in the rendering of the images. (quite often the moon does appear oblong or elongated). As for formats, perhaps when you flatten your final work from the layers, try your "save as" in file type .png~ I've found that the quality of various blending modes and effects maintains itself in this format better than .jpg or .gif Just a thought.
