My English name is [Ambiel].A foreign teacher from Canada said that it was very beautiful.I wonder if [Ambiel] is really good?
A quick search on the internet indicates this is a (perhaps uncommon) surname. While I think it's not one you'll readily encounter, surnames-to-given name is not an unusual conceit in the English-speaking world (Clark, Spencer, etc.) so you should be all right. It's not offensive in any way I can see. If people are going to take a pop-culture cue from this, likely it will be that it has a 'Tolkien-esque' ring to it, a la Tauriel or Galadriel. However the idea of 'good' covers a lot of territory. Do you mean social acceptable in some sort of 1000 most-used names norm? It's an unusual name for that, I've lived all over North America and never encountered it before. Do you mean easy to pronounce or to remember for people you encounter personally or professionally? I think I would probably remember Ambiel, though I might get it wrong, I'm not always great with names. Do you mean pleasing to the ear? I think it sounds pretty, but this is inherently subjective. If you like it, then go ahead and use it! The name police will not come and cart you off. Loads of people have and enjoy nicknames, or different names than their given names, so if you want to be Ambiel at this point in your life and travels, then enjoy it. :D
