Your flow is all over the place in this piece. You need to cut the spacing between notes and the beat dramatically. At 0:40 - 1:12...you really need to do some work there and get everything sounding more realistic and less generic, I would also suggest you adjust the tempo a little bit so you can see what I am talking about.
Your loop is spot on, but the spacing leaves this piece to be desired. The melody reminds me a LOT of Willow on the NES (which is a good thing and earns you 3 stars). Touch this puppy up some and utilize some change-ups and lengthen this piece a little more and you will see some high ratings come your way.
Thx dude, i will care about those spaces in a future..im glad that someone can give me a true review about my work...i was feelin empty because I wasnt sure about what i was doing...yes, I note imperfections, but I rlly need someone to be specific with my weak points. Thank you, very aprecciated. Experiment with chiptunes in fl studio could be a mess. Ps. Srry english its not my native language
