Sentinel Security SystemsLogo Design Contest

Hi, with entry #42 can we try a black background with some subtle gray lines through it?

are we able to brighten up the word sentinel in #42. i like it, just sentinel looks a little dull - maybe what you have done in the symbol you could try with the word? thank you

With #89 can we try making the background like this:
