2 concerns though for you to consider
1 - What is the name of the deck? Is it 'Dwarfs'? If so, that NEEDS to be on the front of the tuck.
2 - Related, it's very odd and confusing to have the name of the studio so prominently displayed on the tuck front. It should be secondary after the tuck name and certainly not as the only featured IMAGE. Having a bunch of the characters popping out of the hole, perhaps even fighting or being aggressive would be ideal here. Something as simple as picking one of the characters from the court cards or a pair of axes would fit better there.
NOTE - I was under the impression that dwarves was the technically correct plural version, but I see you got it right with dwarfs.
Dwarfs is the standard plural of the noun dwarf. Dwarves is a newer variant popularized (though not invented) by English author J.R.R. Tolkien in his fantasy fiction works, including The Hobbit and The Lord of the Rings. The Tolkien spelling is appropriate when referring to little people in fantasy worlds. Dwarfs is better everywhere else
