Thank you Marty and Mario for your insightful reviews and criticisms. I could have actually put the drums louder but I found it quite monotonous and it is set back. I should plan more drum breaks in the song and maybe try the Stem function of band in a box to improve the sound, is to be seen. For guitars, it's true that a less aggressive more jazz guitar could have been a good choice but I wasn't on top of it. Thanks again for taking the time to listen to me.
