Alright, listened to them.
I got some NWN Vibe from the first one (exploration). Might be the tone, not a bad thing though. The hammering sound was a nice element which I really appreciated at first but which ended up getting on my nerves. If I imagine this as exploration music, I'd probably turn it off because it loops a bit too often. Maybe include some variation in the hammering?
The battle theme was a bit odd, like it didn't know where to go. You've got the same hammering and the build up at about 0:10 is a nice touch. The music then transitions into chiptune, then noise (referring to the genre) before it gets even more busy. I have no idea what the hell happened at 2:05 and I closed the tab afterwards.
Overall, the sound texture could probably be worked on, make it a little but more fluent at points, lessen some of the repetitive elements and throttle down on the dysharmonic elements at 2:05.
I'd like to give an example. Bioxeed - Incomplete Objective
. Notice how the different sound textures transition into each other seamlessly and there's always one dominant aspect with the other aspects taking the back seat for a bit?
In your battle tune, all those aspects happen all at once and fight for dominance over the song. Keep in mind its all opinion and I'm not a big fan of that particular genre.
All in all, there's promise. I liked the first example better than the second and think it could be really interesting with a few tweaks.
