Good first draft Shin - very nearly a level 3 but needs more depth in analysis. This is what level 2 looks like in the grading criteria:
Going through the criteria, here are your action points:
a) (Overall podcast) There are changes in environment during the recording which are noticeable and there are noticeable edits too in places.
b) (Question 1) You need to acknowledge the genre of your film and then discuss your film in relation to the conventions of the genre. "love" is not a genre. I would place yours as a drama and the theme of love is similar to other films so you can't claim it's new. But what you can do is emphasise the influence of Tamil a bit more here. You should also discuss how your narrative is conventional/unconventional in the sense of the beginning middle end (equilibrium). You should also discuss your wonderful work on the soundtrack here.
c) (Question 4) Be specific when discussing skills in the various stages of your project. Generalised comments don't get you marks. Reflect on your specific experiences with the technology.
d) (Question 2) The ancillary tasks to be discussed here are your poster and radio advert yet you don't reflect on them and how they support your film.
e) Again, general comments don't get marks. You need to pick out specific points from the feedback and discuss how they helped you think about and reflect on your work. You must also have detailed feedback on your final film from at least 2 people.
f) (Overall podcast) If you listen to a podcast like this one http://www.guardian.co.uk/film/audio/2011/dec/08/film-weekly-podcast-carol-morley you'll know they have an introduction and a context so a certain level of skill is required
g) (overall podcast) communication is not an issue because you are clear but what is a issue is the lack of depth in parts of your analysis
