Last three are kind of interesting. The balance could be a little better, though.
Thanks for the positive feedback. (I guess it was such

)
What do you mean by better balance? ... I'm willing to draw better drafts if it is possible

Those drafts are kind of results of an evolution: started from "NEM" ...

And the same for the currency symbol. They are usually one letter + (long/short) lines like $, £, .
I was thinking that a letter is too common for NEM. But on the other hand it shouldn't be totally new symbol, which is coming outside of our alphabets
But, I'd still develope the images, if they have any perfectible draft
