Love your handwriting. Wondering how this would look if some other material than paper was used, so most of ink wasn't absorbed into the paper and there was some shininess left in the writing.
it fits the challenge, but due to the nature of the pen i think it would be difficult to make it Cor! Wow! in a photographic sense. the 24k bit is creative (you read it, next word in mind is automatically the challenge title) and technically there is little wrong with it. just feels a little cold - 4.
Clever idea, though I am sure whether it is strong enough ! It certainly meets the challenge, but as a picture I find it bring. However here is my voting ....
