Haiku
I need to know if this follows the rules of a traditional Japanese haiku as well as if it's any good. My Japanese is still very much at a beginning level but it's very important to me that this haiku be in Japanese and it will be read by a fluent Japanese speaker.
I have made sure to add a Kigo and a Kireji, mostly I am concerned about if it follows the 5-7-5 rule and if it makes any sense.
Thank you for any and all help

Answer

Thank you so much for taking the time to help me! It seems I still haven't quite got it so I will keep working.

Answer

Let me answer one of your questions first. I suppose your haiku is 5-8-8, if one reads it as follows.

よさむづき さびしいおもいや いっしょにたいよう

I like your haiku, which, as a result of the kigo "夜寒" and the kireji "や", evokes two images in my mind: (1) the lonely-looking moon in the air at a cold winter night and (2) the merry-looking moon accompanying her sun on another day. I'm not an expert in haiku, and I can't tell whether it's written within the rules, though.
