The image seems to be a painting of some sort of ethereal feast with several heavenly, spiritual, or mythological creatures present. There seems to be an angel with it's wings outspread, three women whom light is shone upon to give a positive connotation to (one or two which seem to wear a crown or jewelery suggesting royalty or high status, and one or two slightly evil or demonic looking creatures (or decorations, i cannot be sure) in the background that are red, angular shaped, and have slanted eyes which further lend to the evil and distrustful sense about them.
The table appears to be long and gold coloured, although the texture hints more towards wood. It seems to be composed of several planks put together. There are what i thought looked like grapes in a fruit basket center on the table, as well as several dishes. There are what appear to be flowers, vases, and perhaps wine jugs/pottery in the foreground/front of the image.
The overall tone seems ethereal and awe-evoking in the center of the image, mostly created by the presence of the angel and her wings, as well as the use of light and gold colour in the image. There seems to be a hint of evil or foreboding in the background as the light seems to wane towards the outer edges of the image and and adopts more of a red tint as it shows some strange looking creatures or decorations at the back of the image.
ok, i got carried away. felt like an AP short answer. i guess i'll leave it be.
TL;DR - fancy looking feast of the gods, with some weird things at the back.
