This poem is fairly good. Its got its feeling and all in it, but it doesnt flow that well. Try sticking with a regular stanza. ABCB, AABB, ABAB format.

ABCB meaning the 2nd and 4th verse rhyme and the 1st and 3rd dont.

The grass is green
The Sky is blue
Laying in bed
Thinking of you

That would be an example of ABCB. Try picking one of the formats and stick with it. You'll improve greatly. Other than that pretty good poem.
