I really dig the desert theme you got going on! The sitar sounds really nice and everything is pretty catchy! In my opinion, I think the problem might be that there isn't enough going on. That, or there isn't that thing that adds a new sort of depth to the song. Perhaps another sort of string instrument, like an airy sort of guitar? Or maybe something on the heavy side like a quiet, rumbling sub bass?
Overall, it's rather good, but there's way to make it more interesting. What to add though, is up to you. Find other tracks similar to yours and use those as inspiration!
