Thanks for sharing your notes. It looks really good, I think. Is it possible to change orientation of the paper in that app? Then you can even learn how to write essays writing top-down 
(… there are couple of rules with spaces and stuff when writing top-down.)
Feedback
If you like, I have some minor remarks. Feel free to ignore them or double check with another durtle or Japanese native if possible as I am only a Japanese learner myself
First sentence: proposal:
- either: 日本で寿司を食べたい
- or: 日本に寿司を食べに行きたい
The second sentence sounds pretty strong. In a conversation I’d definitively be curious why you are prohibited to go there the next day. → Do you know about koto ga dekiru ? Maybe you can say something like:
- 明日とても忙しいから、行くことができない。
Also in the next sentence you used an indicator for future (asatte) and past tense together. Unfortunately you can’t do that in Japanese. You have to use present tense here
Oh, and do you know about the “sentence a day challenge” we have here in the forums? You can join there if you like. Durtles also give feedback if you ask for it.
