had a listen to "Time to Start" - overally sounded pretty well mixed, and the timing of the instruments was very good..
As it isn't my genre of music, I am not sure comments I thought to make whilst listening are relevant.. maybe someone who is more competent than me in your genre (which I hear as leaning towards metal) can offer more suggestions. Why I say this is that your mix and arrangement might be spot on for your genre, so I can't comment. All I can say is that that first track that I listened to sounded good to me, and well performed and arranged.
Hope my lack of comments helps
