ok my uncle jimmy once told me about one of his experiences when trying to communicate to his angelic guide or something its like a spirit guide, anyway he said when he was trying to communicate to it, it suddenly appeared or its presence appeared, he said it was like a 30 foot tall tower or something, im bad at explaining, and when he visualized it it had no eyes and it freaked him out, I asked him why not talk to it, and he said when you think of something angelic you don't think of no eyes
Sometimes spirits, at least the ones who do interact with us, take forms that they know we'll be comfortable with.
Others just don't bother, and the results of that approach can certainly be interesting!
Besides, when most people think of angels, they don't think of a four-headed beast with wheels?but that's what's actually written out in the Bible. In paintings, the feathered wings could be an influence of Greek paganism: the muses, the wind deities, and Nike (goddess of victory, not the sports shoes), were all traditionally portrayed as human-shaped with feathered birds' wings and that influenced the image of angels.
They could be neither. They could be eyeless towers. That would be interesting. Just because it isn't a recorded form of a categorized "choir" doesn't mean that it's impossible, but I'd be wary of sharing that information with people who are precious about traditional names and images following an already-established canon instead of discovered through personal experiences like that.
