Give them their first beat!
One thing that annoys musicians tremendously is composers writing a nice, soaring line for them, but not allowing them to play a last, short note on the first beat of the next measure when their line has ended. Somehow we are internally wired to expect our parts to finish on a first beat. The most prominent example of this is the end of most pieces: After a (lengthy) final cadence they tend to end with a big "bang" on a first beat. Try to compose this way in the whole piece and your players will have much more fun playing your stuff!
