Like ZacD said the scale is off. Skulls and eyes too big, columns too small. The overhanging cloth seems flat in the middle, like gravity isnt affecting it. Also, if this is supposed to be a food stand you should have baskets and containers of sorts on the table. The eyes should be in them, and the skull could have a price…
This is pretty cool, man I totally agree about scale issues and containers for the food items. For the skull I'd say you should keep the middle seam in mind a bit. It's a little distracting with so many cracks right there, so I'd lay off it a bit. For the brains I think you should handle its surface treatment way different…
