I understand that the difficulty of a passage is quite subjective, but all the same I need to have some idea of what I'm asking. This passage looks OK to me. It sits in the middle of the register, is bowed predictably, and uses a reasonable collection of pitches.
I hope to hear that it will be dramatic and exciting. Hard is OK, but not unplayable. Is it beyond the level of a skilled amateur orchestra? Is it within the expected difficulty level of a mid teir state orchestra in the US?
The tempo is fast, at least ♩ (quarter note)=144
