Most of those are pretty bad, I think. I guess they don't have any real-life experience?
Not that I'm one to talk...
(I like the circles オテント丸 (otentomaru), STEED ENTERPRISE, hinketsu elevator/Ueda Hajime, mutekei fire/安倍吉俊 (Yoshitoshi ABe) and some others I'd have to look up... none of them are adult-only)
About your English, how's your pronounciation? I know Japanese people who were born here who can pronounce both languages properly, but unfortunately I've never met anyone Japan-born who's good at English.
I have a song in English by Ai Maeda; she's really good at English, but leaves out the 'r' and 'l' in most words. They're important!
