Ok there we go! My personal view in a huge post. Only looking at the design/compostion (beats, sliders 'n spinnahs) of the map.
Winter
00:12:153 (1,2,1,2,3,4,1,2,3) - copypastehorizontalflip, uncreative & predictable meh
00:28:153 (1,2,3,4,1,2,3,4,1,2,3,4,5) - copypastehorizontalflip, uncreative & predictable meh
01:38:153 (3) - Doesn't fit the style of the map at all. End with a smooth slider.
An average easy difficulty. Could use some more sliders (there are only 2), beginning players like that and it could make the map flow better/look better. It's up to you to decide where you place them.
Fall
00:02:432 (2) - Don't let it overlap with the previous sliders and make sure it curves in the middle of the slider.
00:30:543 (5,6) - Doesn't fit the use of soft hitsounds. Why? They're too loud and don't fit the sound you're mapping it to.
00:34:666 (1,2,3,4,1,2,3,4) - Kind of kills the flow and feels uncreative to me.
00:41:413 (3) - Unstack this one, fits better with the music.
00:45:785 (5) - Remove this one and continue with 1/1 beats. Because you didn't put a slider here @00:41:288 either.
00:48:534 (5,6,7,1) - Ugly shape
01:01:278 (6) - Move down a little
01:01:653 (1) - Add a whistle here & @01:04:276 (7) etc. A hitnormal sound works too.
01:04:651 (1) - Put a slider here like you did @01:01:653 (1)
01:06:525 (5) - Make it curvy?
01:07:650 (1) - Move it to the same place as the previous (4). Looks/plays better.
01:11:772 (2,3,4,5,6) - Doesn't look nice. Do something cool with it.
01:19:644 (1,2,3,4,5,1,2) - Doesn't work for me. It looks ugly and is way different from the shapes before it.
01:25:641 (1,2,3,4) - Those two sliders could look nicer don't you think?
01:31:638 (1,2,3,4) - Those two sliders could look nicer don't you think?
01:37:635 (1,2,3,1,2,3,4,5,1,2,3) - Best part of the map. Flows well and looks decent.
Summer
Hey this has sure improved alot.
00:09:254 (1) - Make this slider look nicer/more curvy (ilikethat)
00:33:921 (2,3,4,5,6) - Too lineair for this style
00:49:254 (1,2) - I'd like it more if you didn't stack these. Kills the flow.
00:50:254 (3,4) - Same here & 00:51:143 (5,6) - Same here & 00:52:254 (7,8) - And here
00:59:238 (1) - Needs a normal-hitwhistle to give it some extra power (more boom~) 01:01:238 (1) - Here too & etc.
01:11:572 (1) - Let it face down. Might seem unneccessary but really does play better.
01:13:238 (1) - The soft-hitfinish sounds good here. 01:14:238 (5) - But not here and the beats after it. Go for a normal-hitfinish on the boom spots (more boom~)
01:41:238 (1,2,3,4,5,6) - Same thing with the stacks I mentioned somewhere over there ^
Spring
00:04:318 (5) - Could looke nicer (: (I could keep saying that for every slider that doesn't have enough curve but that would be alot of writing so I'll let the slider thing up to you. You know how I like my sliders anyway)
00:48:409 (1,2,3,4,5,6,7) - Ok now these slider don't fit the style of the map at all. When I suggested you could use these it was for a different styled map. It's weird to use semi-lineair sliders like these in this map.
00:51:837 (6) - These are ok (couldusemorecurvethoughderp)
00:52:980 (1,2,3,4,5,6,7,1,2,3,4,5,6,7) - This looks pretty messy to me. I can't really explain, I just like them different, more organised.
01:05:931 (7) - Nearly invisible. Try something different with less wide spacing and less overlapping. Or just remove the note.
01:07:550 (4,5) - Make it the same as 01:06:979 (2,3,6) but flipped ofc.
01:11:169 (9) - Use a normal beat instead
01:29:834 (2,3) - Overlapping like this is a no-go.
01:30:976 (6,7) - And suddenly there was 1/2! Keep following the melody here.
01:34:119 (1,2,3,4,5,6,7,1,2,3,4,5,1,2,3,4,5) - copypastehorizontalflip, uncreative & predictable meh
01:44:308 (6,7) - overlaps ;(
01:50:974 (4,5,6,7) - Make these the same distance from each other as 01:44:023 (4,5).
There you go.
