You're right. The instrumentation makes a huge difference in their feeling. However, both clearly demonstrate your angular, bold style. They are both from the Marko Era!
Some phrases in the first half of the piece have more of a woodwind phrasing to my ears, and aren't quite as effective on strings. However, the second half sounded to my ears as more matched to strings. Some lines were a bit long for the woodwinds in the second half.
Anyway, those are my initial reactions. As always, I really enjoy your use of rhythms and scales, whatever the instrumentation.
