hi, M4M for your queue~
[General]
it's cut? not really good end of mapping imo o.o will really like if you map full ver song although it's pretty late by now =="
also for Left 4 Dead tag it should be "Left_4_Dead" (example in ranked one is - t e n n y a - , her name in tag is -_t_e_n_n_y_a_-)
[Normal]
not reacommend slider velocity change in easiest diff, consider to delete 0.75x green line section 00:25:378 (3) - place upper and will become like this
http://puu.sh/3oK09.jpg00:25:978 (4,1,2) - make them symmetry? it will look neater
01:00:178 (3) - stacked by 00:58:978 (2) , move it lower, besides 01:01:378 (4) not really symmetry with 00:58:978 (2) ('cause you copy paste (3) slider from (1))
01:30:178 (3) - ctrl+H, it will look symmetry with 01:28:978 (1) and neater
01:49:378 (3) - ctrl+J, same reason as above and it still looks good
http://puu.sh/3oKk1.jpgoverall pretty good, but still need more mods for design
[Hard]
00:00:178 (1) - add clap? (comsider clap use at 00:04:978 (1) )
00:02:878 (2) - clap at slider's start not reall fit, remove it
00:05:878 (2) - prefer whistle at slider's end
00:06:778 (3) - clap here is pretty good
00:13:978 (2) - make it further from 00:13:378 (1) ? consider jump at 00:11:578 (3,4)
00:23:578 (3,1) - 1,96 then 0,86? too far difference and weird imo, make 00:24:178 (1) further maybe?
00:28:528 (3) - not really legit anti-jump, make the spacing with 00:28:078 (2) further than now
00:46:678 - add a note here, weird gap
00:57:028 (2) - curve it better, like this
http://puu.sh/3oLFe.jpg01:01:078 (4) - stacked with 01:00:478 (2) , move it somewhere
weird jump pattern at beginning but it become better at the end[Insane]
00:04:978 - 00:06:778 - fill with some notes, orz. too empty
01:15:778 (1,2,3,4) - something like ? (better jump pattern, switch (2) and (3,4) placement)
http://puu.sh/3oM3m.jpgcan't play insane much but this diff is good imo I thinks that's all, good luck then~
