You have a very good start on this Honeybee! (By the way, welcome to EB!)
One thing you have a plentiful amount of is fun interior design elements, like the angled table, keg, and the crystal balls. You did a great job with the SNOT floor as well.
Some improvement ideas:
1) I would definitely recommend deeplinking 2 more images to the post, so viewers don't have to click on a link to see them.
2) Writing a little back story for your entry would give more insight about your entry, like why are the minifigs skeletons for example.
3) The black brick wall might look better in brown if you have enough.
4) Your lantern on the left looks great, but I'm not a big fan of the red hand sticking out. I know it's meant to be a flame but I think leaving it bare might look better.
5) A minor point, putting some tiles on the front where there are studs showing would match the sleekness of the rest of your entry.
=====================================================
I think you did a superb job for a first MOC. You've incorporated lots of detail which is sometimes hard even for experienced builders.
Good work, and all the best for the contest!
