Need opinions on a Gym Leader theme

Personally, I like the theme quite a bit-- it's got a nice mix and is structured in a way that reminds me of the main games. I'm definitely no expert at music myself, though, so I feel a bit hesitant to make any big suggestions. If it's fullness you're thinking about, I find that the backbone of any powerful track is in a strong melody.
There is one point that really stands out with me, though: the way you weaved the low health beep into the low health version. I thought this was a really clever way to make use of a sound that I found pretty darn annoying when playing the Pokemon games. It's a cool touch that compliments the track surprisingly well.
Hope this feedback was helpful!

I'll give it a listen when I can! Curiosity is taking over though - what game is this?

We're calling it Sandstone and Limestone. Just something we thought would be fun to do in RPG maker, nothing big.

So it's in concept stage? o3o Either way, good luck with it!

These are actually pretty darned awesome, great themes! It seems like you have a couple great songs! I am definitely not a remastering pro, but I think I can try to steer you in the direction you are looking for. Maybe. Solely suggestions, take them as you will!

First off, are you using FL Studio? Stereo separation is a wonderful thing if you are, it's the little knobby thing shown below:


I *believe* this is called stereo separation. It is delicious and allows the right-panned stuff to pan, well, more to the right, and likewise for the left. 
Utilize panning in your composition, and then hammer that knob to the left to adjust separation. It is beautiful. Opportunities for panning could include that piano piano and music box accents and arpeggios, the hi hats (to a lesser degree), and even the french horn. Play with it to your liking!

Also, I am quite naughty and break like 50 remastering rules in doing this, but I use an FL Parametric EQ 2 plugin in the master channel of my songs to help spice things up a bit: 

Feel free to load the plugin and create a similar configuration, or one to your liking.

A couple other suggestions -

• You seem to be like me with the soundfont oboe when you use the french horn - I would encourage you to use a little bit of another brass instrument in the melody instead of just the french horn. Try playing with some panning, doubling of instruments, and harmonies. You might be surprised at what you come up with! 
• Select the kick notes and pump up the velocity just a bit - a little more kick goes a long way. And nice job on creating an interesting percussion line, that's something that I always find REALLY hard to do and that I try to work hard on.

I don't separate the Master knob though, a bit in Maximus on mid/highs and on other instruments. ^^ Just how I do things.

It sounds really good so far! I always struggle coming up with melodies for battle themes but this is really good. I think the problem is that the lead instruments are too smooth and too far back. If you can bring up some sharpness (raise highs on lead instruments slightly) and adjust reverb to bring the leads closer to the listener it should feel a little better. As a side note, would you be upset if I borrowed your idea of "low health" versions of music for my fangame? I really liked that in B/W (one of the only things I liked about gen V, actually...) but it was only one song instead of a new version of every song.
