Hm... without listening yet, one problem: "There can be only one" is, IIRC, a copywrited title.
Now... D/Ling to listen.
There Can Be Only One:
Opening: The intro 7 seconds or so is good, but the tones that pick up afterword sound a little... blah. Musicly its good; it just sounds like a midi file or something. I definatly like this piece however.
The Bass line around 1:10 is
nice. Very dramatic feel, and I can feel it deepening to a climatic something. 1:35 to top lines are nice, too. Like the way you shifted. And the lower lines at 1:43 ish are nice. This piece is
going somewhere! This
definatly belongs as either combat or "high combat" (e. g. orion, monsters, etc). 2:30 (middle of) the cord sequences are nice. I like how it tapers down without losing suspence. This is very good music. I'm tapping my fingers to it, in spite of myself!
Man, it just ended!
War Mood:
Not good for schedular (SP) screen or pre-combat, but as a theme music to some hostile race... nice.
Eh... starts losing that feel around 0:40... Feels sadder, more haunting. Main flaw seems to be its a little to monophonic. Very little harmony until later in makes it feel a little bland. Since it'd be playing reguraly it might be good however. Especially if you have to listen to it for "hours on end"

. Try and lower the overall tone - the high pitch of the piece may just be my machine (its known to have interesting and unusual problems) but it'd be annoying in the long run. If you could, just try lowering the pitches about half and octave.
3:00 big shift! Loses at 3:10... but the new feel is also good. 3:20 Ooops, spoke to soon about loosing feel. Maybe cut the stuff between 0:40 and 3:00 and place a new intro? (NOTE: All times are approximate) Other than that, seems OK.
Story battle V2:
Ooooooooh! Nice. The drum pieces in the background hit the spot... I can't really finger any other changes that those harp chords and it, but they make it very nice. (Remember: A small change can have a huge effect - and I often confuse "huge effect" with "huge change" when asking for something, often because I'm not certain which is needed).
This could definatly be regular combat music, and use "only one" for special battles. 1:50 I noticed a driving drum beat - nice. Very nice. The drum beat is new, I think, and definatly helps keep the piece moving.
2:50 I like the moving line. Does ruin the "mood" though. While its a nice segment, its too "slow" for battle. Its too calm. Its too... sad. Try increasing the speed through that section (maybe half again to twice the speed of the moving line). 3:50 it starts to pick up speed - don't increase that section as much. 4:10's slow down would also need to be picked up. New intro into 4:20 could make or break that part. Depending on how you enter it, could be good / bad for battle. End is... OK.
DISCLAIMER: These are written as I listen to the music, so times are only approximate (assume 1-2 seconds delay in switching to check the time, and maybe 1-2 seconds added by the program because it tries to add time around the edges for some reason).
Oh, and what are you using to do these on? Any chance I could get some copies for free? (I. E. are they freeware or something similar).
