[General]All Diffs are mapped up to ~1:35min but the song is 3:14min. Please shorten the mp3 to an acceptable timing point like 1:45min (5s fadeout)
Combo Color 1 is too dark. You can't see the approaching circles on some of the BGs. Pick something a lot brighter or get rid of this color (use just 3 overall)
[Easy]00:06:327 (2,3) - spacing
00:10:582 (2) - ummm...whats up with this slider? looks strange...why not use a nicely curved one?
00:13:923 (1,2,3) - Try curving the middle part of these long sliders exactly around (2) as this will look much better. Something like this:
http://puu.sh/2BTF00:19:637 (1) - ugly. Curve better around (3), adjust spacing of following note afterwards
00:32:698 (5) - angle between the points is too small. Make it a bit softer and this slider will not look as if someone kicked it in the nuts.
00:35:963 (3) - curve exactly around (2)
00:56:371 (3,4) - better use a slider instead...
00:57:392 (5) - ...and turn this into 2 circles
01:02:086 (2) - again, don't move the grey sub-point after the starting point so far out. It makes the sliders look weird if it is <90°
01:20:045 (2) - is not straight down
[LRJ's Normal]00:22:902 (4) - move ending point to 102/274 to fix the spreading gap between the two sliders AND curve (4) more exactly around (3)
Otherwise flawless
[Pereira's Hard]00:26:984 (1,2,3,4,5,6,7,8,9) - Maybe seperate every stack by adding a new combo (1,2,3,1,2,3,1,2,3) to make it more visible
00:33:922 (1,2,3,4,5,6,7,8,9,10,11,12) - ^
00:40:861 (3) - oddly placed slider. Better place and curve it in a way that makes the overall curve of (1,2,3) more even
00:42:902 (X) - why don't you map this? It plays weird and misplaced if you leave out this note...
00:45:351 (6) - move ending point to 291/72 to make a nice curve with the following combo
00:46:576 (4,5) - It fits the song much better if you delete (4) and let the slider start there (keep the endingpoint of this slider on the same red tick it is now)
00:53:718 (1) - can be curved better around (5) and keep starting point + ending point at the exact same level
[Necro Fanatic]Could use some better object-placement in general. Come up with some interesting notefollow-patterns and try to close most of the huge gaps with sliders. Again: Combo color 1 is WAY too dark. Change it please.
00:18:514 (X,X) - definetely needs 2 more notes here. Place circles at the blue and red tick and form a nice spacing-consistent 5/4 stream. This will map the piano exactly. (3,4) just don't make any sense right now.
00:27:392 (2,3,4,5,6,1,2,3,4,5,6,7,8,9) - come on! This pattern is not very creative... Try a dead-end or something else that plays interesting.
00:40:045 (1,2,3) - feels extremely empty. Why don't you use sliders for those parts?
00:45:147 (1,2,3,4,1,2,3,4) - be creative!
00:48:106 (1) - start the spinner at 00:47:392 and end it at 00:48:616 to at least match the song
00:49:739 (4) - weird. Why the strange placement? It kinda stands out as it doesn't really fit to the rest of your map. I suggest keeping this in line
00:53:106 (7,8) - again, why don't you use a slider here instead? Those empty spaces kinda ruin it for me

00:56:371 (8,9) - ^
00:59:637 (4) - the "S" can be done much better:
282,309,59637,2,0,B|300:355|433:356|481:339|481:257|471:192|371:194|371:194|275:192|263:125|261:57|307:28|439:27|461:78,1,720,0|10
01:06:167 (1,2,3,4,5,6,7,1,2,3,4,5,1,2) - this is better than before but could still be more interesting
[Eternal Wandering]I love you Kite!

...fits like a glove. This is beautiful!
1~star for the good mapset, keep it up!
2~stars for the awesome [Eternal Wandering]
