Is this a successful haiku?

[Mitera Nikkou]

Check my signature. I'm not good at any kind of poetry, and beyond rhymes have next to no understanding of it all, so I was wondering if anyone could take a look at the crack I took.

Let me take a look
it follows five seven five
sounds like (a) haiku

Then again, 5 - 7 - 5 isn't all that is required for a haiku, but thats really subject to interpretation.

[EDIT]

The generally accepted form is no more than 3 lines and/or (not to sure) 17 syllables max, some word associated with a season, and something to indicate a pause of sorts, to add contrast
