That's a perfect opening! Did you mean to leave 'sun' lowercase, though? If it's the Spring sun being personified rather than just Spring, than you can make it Spring Sun.
'Skin' and 'kiss' both have have the same 'ih' sound which creates assonance. I've seen that a couple times so far in your work, and I've always loved assonance in poetry. It adds a nice sense of uniformity without coming off as forced.
I love this whole poem, but especially these lines. I don't know, they just work so well together.
