Hi, of the two tracks, I prefer the first… The vocal has a great energy to it, and I like the clarity in the vocal.
Both mixes, to a greater of lesser extent have a lot of energy in the low mids, which can tend to make the mix sound slightly muddy. That is more the case with the second song, as I think the guitar sound might be a contributing factor there, in combination with the big Ultravox-style synth bass. I think if you pulled a little around 300-400hz out of the guitar, and some 250hz out of the bass, the mix would open up quite a bit.
The first song has quite a catchy chorus to it, which I enjoyed. I’ve noticed that the catchiness of a chorus can really be enhanced by adding some harmonies behind it - I would have loved to have heard some there.
