Slider Curve Warning:
00:27:832 (5) - The slider curve will not work correctly in older clients with it's current shape. It's best to avoid making full circles with Perfect Curves and instead do shapes like this with Bezier's. Here is what this would become on clients from before late 2012.
Normally I would tell (you) the mapper to fix these, but this is your first map, and honestly it's really nice. I don't want you to think that you messed up, this is not something the average osu! mapper ever has to consider. This only really applies to Titanic, and I'm anal about it because I don't want replays from people playing on older clients to show sliderbreaks when watched on newer clients. Here is another example showing how gameplay would change on this slider on your map
You can do a quick check on any slider to see if it will become messed up by clicking on it and swapping between S and F. If the path is hugely different, then it should probably be changed. This only works in my modded b20130303 client though.
I have made a similar shape using the Bezier type shape. Please open the .osu file in a text editor like notepad, and edit this line:
139,259,27832,2,0,P|141:198|65:201,1,122.25
To this instead:
139,259,27832,2,0,B|161:237|157:194|124:172|88:183,1,122.249999642372
Here is how my Bezier compares to the Original Slider

General Mods:
I recommend applying the above changes first
You will need hitsounds, they don't need to be super complex. You could try asking Kagamine Rin if they are interested in hitsounding it, but I know they have accepted a few already and their backlog might be long. This song shouldn't be too bad to do on your own though.
01:53:315 (4) - I don't think this should be a reverse slider like this, just keep it simple with a 1/4 slider maybe something like this:
