First rule of editors (for me at least): look through every menu for things that can save you work.'Sp, I fixed some of the issues like the overlapping notes and the circle size and made it on Easy difficulty instead of Normal. A friend also helped me make a short sample of the Normal difficulty, but I think it's too hard. Also, about the shapes being non-symmetrical...there was copy-pasting and rotation? That would've saved me a lot of grief.
Anyways, it's a bit more updated now. I'll fix the other issues later this month, as I'm busy(last month of school, exams and all), but I'll try and finish this and make more difficulties.
The second note is slightly offscreen, you might want to move it just a tad higher. If I were you, I'd set slider tick rate to 2, it fits on the sections where you placed sliders. The sliders at 00:16:XXX are somewhat ugly, try making them a bit more like the slider at 00:20:500. It looks better when the circle is in the middle of the slider like there. Some of the positioning still is confusing, like the one at 00:41:750. There's still no preview point, and the audio leadin is different for your diffs. Try to keep it consistent (although I understand since someone else did the Normal, it's probably better to change it). Background is still the wrong size. You probably want to add "Teara" to your tags if you want to keep a difficulty made by him/her, it's normal to do that for people who make guest difficulties. I dunno if it's a good idea to start the notes on the Normal before the song is even audible. Also in the Normal, the slider at 00:12:875 sounds a bit odd. I'd move it forward or backward 1/4th beat. And yes, that Normal seems too hard. If you want to keep it like this, call it Normal+ or something. You could also make it the Hard, but it would be a somewhat easy Hard. IMO this song is not really fit for high difficulties anyway, it's too calm for that. For the Easy, the hitsounds seem a bit odd. Some parts have nearly no hitsounds, some parts have the Clap sound on every single hitobject. Some of the old criticism also still applies, like the overly long spinner and the oddly sized background.
