Your attempt at Haiku has succeeded. You have captured a moment in time. This reminded me of mornings when I am out camping. I so enjoy the mornings when the sun first peeks through the trees, to warm my face.
Technicaly, while keeping the traditional 3 lines, the poem departed from the 5-7-5 syllable count. I have read 100's of examples of english poets doing just that. The objective, in Haiku, is to accurately capture a moment, image, or event with the least words possible. Clearly, you thought about this Haiku a while before posting it.
