Hi,
Some really nice designs there.
I particularly like the symbolism of #84.
Not so keen on #78 (looks a bit like prison bars), #79 (too boxy), #82 (bit cheesy) or #88 tho'.
I quite like the colours of #88, #85 & #86.
I think unless the symbolism is really strong the font will need to be as big as #79. I quite like it stretched out like in #80 as well but it would need to be bigger relative to the design above it.
Hope this helps.
:) Martin
