Resource packs are meant to make the game look nicer as a whole. This means even the most depressing and basic dirt shack will look fantastic. When we get submissions with pictures taken in resource packs, our first instincts tell us that the build looks awful in default and the builder had to hide its awfulness with a resource pack. This isn't always true, but in general, it's hard to tell if something truly looks good or if it just looks good due to the resource pack.
That said, I recommend turning off your resource pack and taking new screenshots. If it doesn't look good in default, it won't get added.
