Nice, thanks. Entry 16 looks good. #19 I also like -- no flair on the inside H. Can't decide which is better.
I like lower case letter in my name.
What about "Photography" starting with the lowercase "p" and running to the "y". And having my p and y in my name being the beginning of the word photography?
The film sprocket holes and the city might be too busy, but maybe not. What about the city sitting on top of the H? With little windows maybe?
Or the H could have city windows dotting up to the middle of the H which then turn into bigger, evenly spaced sprocket holes...
Anyway, nice work!
