I absolutely love this poem and find it very ... idk a word for it but it's most definitely good!

To ponder, is to reflect.
To reflect, are thoughts of the past.
To think of the past, is to regret.
But time never regrets.
Thou mortals always hope that time would not be around,
But it always is.
And will still be around.
Fret not, waste not.
Reminisce past,
Ponder the current,
Mend the future.

I like the idea behind the poem and the poem itself -- it made me feel sentimental for a minute. Though, this would be better as a song than as a poem; I can imagine it being an acoustic song.

"The moon as risen yellow" -- do you mean "has"?

I would, however, suggest punctuation in the lines that are not questions, wherever necessary. All in all, a good first poetically-styled thing!

I like this. It comes across as sweet without being drippy, and, well, is the sort of thing that I go for. Nice.

Good poem, with good images. I liked the second stanza the best. It was nice. Great job.
