LOVE! Sadly I am not a fan of Aura marking at all so not so keen on the fantasy fires myself. Though it works well for Ghastly!

I think my favourites are the Forest Spirits and the Dragon Pokemon pair.

I know the customs on Aramii pretty well - at least those well known enough that you would be outwardly seen to be copying them if you did something similar - and I don't see anything in your designs that reminds me of anything so you should be all good there :-)
