Nice program but I feel that you need to find two more pieces piece to end each part. It is usually good practice to end with some kind of "bang", totally drench their senses before the interval so they anticipate the 2nd half, and finish the 2nd half with something big so they demand encores, then your encores should encourage them to want to come see you again when you perform! Two more 3-5min pieces would be great, something really exciting. Ending with something long is usually not as effective to get an audience response than finishing with something that is shorter, of course this is a generalization and you can by all means end with 10+ min pieces, however for the average concert goer I believe they appreciate concerts ending with something "bite sized".
