Hi! Let's talk about some issues with the map in it's current state.
Here is a link to the Titanic Ranking Criteria:
https://osu.titanic.sh/wiki/en/ranking_criteriaYour diff is 5.83*, that is an Extra by Star Rating, not an Insane. I think the diff name should be changed.
Decimal Difficulty Settings are not allowed on Titanic, as older clients cannot read them. Please change the CS to be 5.
Currently your set does not have enough difficulties to be ranked. The ranking criteria states that the drain time of any map set for ranked must be at least 90 seconds. Your current map has a drain time of roughly 80 seconds, so you need another difficulty. Also, the ranking criteria states that you may not have a gap in difficulties. So you could add a proper Insane diff for example, or a higher diff (but I personally don't think that makes sense in our case here) and you would be good.
Your map is missing tags, you need the genre and language at a minimum. Adding the source, album, and other relevant things would be good too, if you are not entirely sure what to add, compare against a ranked set of this song on Bancho.
Your map needs to have the epilepsy warning enabled, it includes bright flashing elements.
Your map utilizes Perfect Curve sliders, which are highly discouraged on Titanic. This is because older clients do not have this curve type and will display them improperly. Luckily my modded osu! client has a built in converter which you can use to convert those sliders to the far more compatible Bezier type. In my modded client you can select all objects and do CONTROL + SHIFT + C. You can use the Automatic Converter option and hit Okay. This will keep the slider shapes nearly identical, but make it work on clients before 2013 properly.
https://osu.titanic.sh/forum/23/t/560/ Your storyboard is huge, and takes up way more space than necessary, this is because all images are in the png format
The following images can be converted to jpg at 100% quality with no noticeable quality difference. I have included a link below to jpg converted versions of these images. Any images that need to be png can be left as is. Another thing, you have an image called "Normal" in your SB folder, which is identical to the image of the main background, you should instead use that instead of this duplicated file in your storyboard.

Make sure to update the references to the new file names in the storyboard .osb (change .png to .jpg)
Let's talk about the actual map now
00:17:281 (5,6) - This rhythm does not seem correct, in all previous parts you emphasize the large sound effect at 00:17:386 with an active click, but this time you instead have this sound land on a sliderend making it passive. Change it so that this sound is active with either a sliderhead, or a circle so it stays active and consistent with 00:10:043 (1), 00:10:672 (5), 00:13:400 (1), 00:14:029 (5), etc.
01:22:211 (1,2,3,1,2,3) - these notes don't make any sense, yeah I get the idea of using the hitsounds to create some sort of emphasis, but emphasis on WHAT? Listen to this section without hitsounds, this doesn't follow the music! What sounds are 01:22:350 (2,2) - supposed to land on by being 1/6? You should create a more dramatic climax in a way that still follows the music.
That's all from me for now, good luck on the set! Your storyboard is cool and your set has potential :D
