I have some thoughts. Not much though, it's sounding pretty good as is.
Cons:- I don't know if you have worked on any mixing yet, but here's some thoughts for you going into the mixing phase:
-- The high end does not sound so clean. Particularly the white noise. If you have done any sidechaining, that could be the problem.
-- Generally, try making the sounds a bit more clean. The sounds are little "low" quality sounding, if that makes it clear at all.
Pros:- I don't have any problems with your melody. It's solid.
- Also, your arrangment is really good too. Just don't forget to add an ending.
Good stuff. Just get yourself an outro, work on the mixing, and you're set. Also, I noticed that your WIP is on SoundCloud. That's fine, but since you don't have a Pro account, I would recommend posting your WIP to a music uploading site, to save uploading time on your SoundCloud. Here are some examples:
https://instaud.io/,
https://clyp.it/, or
http://picosong.com/. Anyway, just a suggestion.
Lastly: I say this to everyone who I give feedback to -- I'm not a very experienced musician, so if anyone else gives you feedback on this song that contradicts what I've said here, it's very likely that they're right and I'm not.
Looking forward to the finished product.
