While I am a fan of more decoration I have but one issue which by all accounts is trivial but I feel is vital for Terraria's sake. The sprites look far too familiar to sky furniture and blocks, the clash of yellow gold and blue is distinctive of sky furniture. I can see two possible ways to work these into the game.
1 :: Merge both fallen star and sky furniture together seeing as they fit so well and not only that but it also makes sense. The stars fall from where... the sky, this could also be tweaked so that stars fall more commonly on sky islands.
2 :: Merge the set with lumite ore. A mix between the shiny otherworldly metal with the rosy gold of stars could be a great combination for a galaxy/shooting star look. Plus the lumite work tabel (forgot the name) could be the crafting station needed.
Just my thoughts on it.
