Silly me, I should have build further on my last comment - I promised myself I wouldn't be vague with my mods anymore.
So, on slider shapes... I said more points equals good, right?
You can take a look at this to see more or less what I mean. In the case of this beatmap, notice how you do "bad" shapes a lot:
To make the beatmap look nicer, I suggest you try to make the following sliders more smooth.
00:25:785 (6)
00:29:937 (7)
00:33:451 (5) - This could be a perfect blanket. Disable grid snapping if you have to.
02:26:240 (7)
02:31:672 (6)
02:43:667 (2,3)
03:21:539 (5,7) - These sliders should be more round, fitting the circles better.
03:24:735 (6)
Some of these don't involve adding more anchor points, but rather, centering the one already in use:
Also, it doesn't exactly affect the slider shape, but it's a good habit to end the slider where the last anchor point is (notice where I placed the last anchor point):
That way, reverse slider doesn't get all messed up, and it's easier to get the shape you want.
On the point of creativity... I felt like in some parts of the beatmap you were just "freestyling" instead of thinking the patterns beforehand. This isn't exactly bad, but it'd be better if some structures were more solid.
For example:
http://puu.sh/YKGJ - This pattern... doesn't feel like it's going anywhere. There's no symmetry or anything, it doesn't feel solid.
http://puu.sh/YKH8 - If it were something like this though, it'd feel better. At least the beats are making a pretty shape up there.
On this aspect, I can't exactly tell you what patterns to change or how to change them, since I would be transforming this in my map. If you did change some patterns around, I'd suggest these (these are the ones who struck me as most "out of place"):
00:21:793 (1,2,3,4,5)
01:32:857 (1,2,3,4,5,6)
01:45:633 (1,2,3,4,5,6,7,8,9)
01:50:743 (1,2,3)
02:14:099 (1,2,3,4,5,6,7)
02:24:323 (1,2,3,4,5,6,7)
Keep in mind this doesn't involve deleting the whole pattern and redoing everything again, just placing the beats with a little more sense would be okay.
In any case, I'd understand if you didn't want to change any pattern; in that case, just keep it in mind for future maps. It can greatly increase the quality of them.
There is one more point I want to bring... the little streams can look a little bit better. Now that we have the "Convert Slider to Stream" tool, it should be a cinch to make these streams more "round".
02:23:365 (1,2,3,4,5)
03:33:524 (6,7,8,9,10,11)
So, I guess that's it. It might look like a lot of work to do, but it's not that much. I haven't looked at Easy and Normal yet, so you could check them yourself to see if they have any of the things I pointed out above. In any case, I believe fixing the Hard difficulty is most important than fixing Easy or Normal.
Don't kudosu this post.
