Nice dude, its starting to turn into something that I would definitely enjoy dancing to at a club or something. Ill break my review down into things I like, then things that have to be changed and finally then artistic suggestions.
I really liked your change of instruments. I also liked the effects that you applied, it makes it sound much more professional. It also has a really nice punchy beat, which is great for a dance song. The ending effect was good.
You need to add another instrument to harmonize with the melody at some point during the song. I was thinking at a natural point around halfway. The song is too long not to add another part or even more to it. You also need some sort of break from the melody into something different somewhere after the halfway point. As reviewers are comparing you to BassHunter, listen to Welcome To Rainbow. He has a nice break in there.
Ok, this is where it goes more subjective and depends on artistic vision. I agree that it is too slow, however, I think what you should do is keep it at that speed for one run through of your complete melodic pattern and then speed it up with a nice transition. I think that would be really cool. I, personally, would also try to patch up the melody even more and make it even more catchy. You have a perfectly fine melody, don't get me wrong, it just is missing that characteristic that leaves me humming it after I listen to it.
You have made a lot of progress, but you still have a lot of work to do. Keep at it and keep me informed, I am very curious to see how this little baby turns out.
