Um, this is me just guessing, it may get you an interview, or possibly them asking for more examples? But if there are lots of applicants and they are time strapped you may not even get that.
Personally it is just a taster. As mentioned before, you haven't actually demonstrated what bits you did, or more thinking behind how you came up with the certain parts, such as with the feedback and implementation. How did you get the feedback? Was user research involved, and if so how was it done? With interviews, questionnaires etc?
It depends what types of skills you are trying to show. At the moment from your current portfolio I can see that you are good at presenting your work, and that you took part in one project. What I'm missing is more detail. What you did, where is the project now, how you reached the certain points. What other projects have you been involved in? What areas do you want to do, or have experience in in UX? What form of user centred design do you follow? A potential employer would want to know your current skills and experiences, they want to be able to have things they can ask questions about, and to gage what kind of level you are at.
Practice will make you more confident, give you a bigger picture, and give you more to talk about to future employers. But you are correct, each position and role will determine the set of skills you need. If you can show you have the soft skills necessary, and are willing to learn and expand on your knowledge, this can be a good starting point :).
