Regals are extremely difficult to keep. If you have not done so, be sure to read up on them and know what is required. Scribbled Angels are pretty much the opposite as far as care .
I would not put two large Angels in a tank. Those two look different enough, but I've heard of people having troubles unless there is a lot of room (like 300g or larger). Mixing Large with Dwarf or Pygmy should work though. I'd go Scribbled and a cool Dwarf.
