Quite reasonable. I wouldn't say the nocturne is easier, as it requires different technique than the prelude. If you haven't done much oom-pah-pah LH passages yet, you will find the coordination of both hands an interesting but attainable challenge. Tips: you can't look at both hands at once in many parts because the distance is just too wide to be both in the visual field. Choose one, and feel your way through the other. Usually the hand with the jump is the one you want to look at.
