frantz

maybe the change of instrument could produce a more appealing effect, but is just "effect" what you look for? i am sure you are fully able to introduce some spicy and meaningful touches into the soloist part without changing the instrument, which is a very fine choice. the arpeggio writting work very nicely indeed, the concert is really enjoyable, but you could just make a further effort to improve it and making it really remarkable. you are not far from that, because the main work is already perfectly fashioned, missing just those bold and original details that make all the difference between a good piece and an outstanding one. maybe a good idea would be to rest for a while till you can gather new forces and inspiration. i suppose that to compose a full concert would be a tiresome effort! when one concentrates too much on a single work sometimes one often misses new and important ideas that float around the focus. just take a time to refresh your mind and later you will surely return to the composition with the needed solution. this material deserves that! good luck! i am looking forward to know the result!
