Hey juanjose1967, I think you have done a good job with controlling this one. The only thing I can think of is maybe lifting the electric guitar up a bit through the solo, possibly. Nice sound otherwise.

I've tried to fix the issues you said. Now the guitar is louder during the solo part, the leadvox is less thin, and I've also given a slightly different tone to the guitar so it could sound better.
About the kick and bass, I've only lifted the bass a little bit. I just like they way it is.
