The first was quite enjoyable. You should think of extending it a bit. The second one wasn't quite as good but still good. The slight accel. was a great addition to the music. But the harshness of the chords through most of it sort of drowns out the niceness of the rest. It's a good addition, but I'd suggest making it a bit quieter, or bring the other part out more. (I'm a noob composer btw)
