Alright I guess I need to channel the Fox in my name and write a bit longer critique. Not that there was anything bad at all but since your songs are very different and I also have different feelings, lets talk about them track by track.
Track 1 (the epic) - For an epic I would have chosen a different arrangement where the brass is more in focus and heroically roaring. The dynamics and general vibes are there and are quite strong. But for getting it more heroically and epic there is happening to much in the second third of the songs. The floor tom sounded a bit hecting and the lines of the background instruments a bit nervous. My recommendation is to stay a bit more on you chosen notes. Let them ring and feel like they having purpose so that the leading melody can have that sonore feeling. Same with the melody. Make every not count more and ring out heroically so the whole song can breathe a bit more and feel more alive.
Track 2 (Ambient) - I feel like the more calmer songs are a strong suit of yours. Like you already shown us in the ambience jam. Your choice of instruments worked very well and with those background vocals (or didgeridoo?) it got quite a nice ambient foundation where the the call and response between the steel guitar and celesta work very well. Nothing else to critique here.
Track 3 (Battle) - This song worked quite well and you might be the first where I have to say that maybe your instruments are holding you back. The composition has everything it needs but just lacks the oomph and immediacy it needs. Nothing that it your fault, but maybe a motivation to finally invest into some newer instruments, since you seem to outgrown those free ones. Another thought that comes to mind is that I would have loved some more aggressive synths creating a more threatening vibe. Something that distorts and growls like a monster following you. Or something sequenced that feels like being on the edge and there could happen something at any times.
Track 4 (instrumental) – Like mentioned earlier those calmer and ambient songs seem to suit you very much and there is nothing I could add or say about it. It was quite lovely and clicked like gears in a clock. The change up between piano/Synth, orchestra worked very well in my books with the piano having a very Silksong like sound that resonated that spacious mysterious vibe.
All in all this was in general a good entrance and demonstration of your abilities. Like mentioned before it feels a bit hindered by the instruments but not in any negative way. A second thought might be to interwove your notes a bit more with more dynamic changes withing each instruments having some creshendos and decreshendos like waves on a sea and leaving more room for other instruments to shine.
