Pretty good!
I Like the flow of the song, and i see you have kept your somewhat repetive habits to a minimum, which is a big improvement from what i used listen to a couple years back.Indeed time has sharpened your skills and you are using them for more unique purposes. Also, I think it wouldn't hurt to add some different tones in the mix like some piano or some strings, but i do like the 8-bit feel i can't say anything bad about that. However I do believe the percussion could be spiced up if you either way if you could make them heavier or flater to compliment some of the simpler tunes and tones. Overall, the remix is well done, nice job on combining 4 songs into a nice upbeat remix. Keep up the good work, look foward for hearing some new work soon.
