I hear some melodic ideas, but without any type of accompaniment (texture pad, strings, woodwinds, etc.), it feels very hollow and devoid of any character. It does not help that the piano is very quantized and piano-roll sounding in track 1. I think you could have done some call-and-response between the two instruments and had at least some harmonic foundation underneath, which you tried to do, but it comes off as harsh and sudden. Track 2 is a bit better because there's a bit more interweaving between the horns, vibraphone, trumpets, and tom drums, and some harmony underneath the trumpet and vibraphone melodic lines. Overall, both tracks are very disjointed and sound quite unfinished. I would recommend learning how to layer, whether it's harmonically or texturally, and then you can start getting into more techniques, like countermelodies and counterpoint. You can definitely fully realize these tracks, but you need more time and compositional knowledge. There are melodic ideas, but they don't necessarily mean anything without all the other aspects.
