Hi Steve,
Nice change with that elipse in L1. I enjoy the haiku and when one can make use of every word succinctly. I'm going to suggest that you revisit three sections of this one:
I awake...equate
flowers grow a thin snow;
must be spring now.The first is the word 'flowers'. Do you mean grow in or through snow? I'd love to see you choose a particular flower to put there, as Larry suggests crocus or perhaps daffodils or tulips?
The second is the word 'thin'. I'd like to see a sub there as well - perhaps sheer, shadow, gossamer or wispy.
The third is L3 - I'd like to see it be a statement moreso than a question: Maybe : Spring's arrival comes ?
So if you opt for any of my ideas (sticking to the 5-7-5 params), you might have something like:
I awake...equate
Crocus peek through shadow snow;
Spring's arrival comes
Enjoyed!
