Actually, since "Gingerbread" and "Elvish" are diametrically apposed, there is no comparison.
The Gingerbread is very gaudy and interesting I guess, as in the old Oriental Curse "May you live in interesting times..." but definitely not something I would expect to find in a D&D environment.
No worries for Estelindis, I seriously doubt anyone would consider the Gingerbread as an inspiration for the works you have generated. Your tileset is reserved and elegant, as well as beautiful. All aspects attributed to high elves so to speak.
However, for someone to actually build a "Gingerbread" style house is a bit of a shock. I mean, can you imagine being a person looking to find a new home for your family and being taken to that house by your Real Estate agent?
