Really nice work work there! The overall image quality is very good! There are only minor things I could criticise about that.
But of course we all know theres a budget and a deadline to hit, and nobody is perfect.
What i would criticise is the storytelling.
It is weird, that you are starting close then take wide shot then going close again.
The viewer has no feeling where he is or how he got there. You could improve that just with a new shot order.
Camera movements could have some more "intention". Its hard to describe and thats just my
personal view but i get the feeling that nice shots are shown just because they are nice. But imho "form follows function"
should be the goal.
Also, and thats subjective too, I think the film is too long. Of course, if the client explicitly asks for that, you are bound to it
but if possible, for the next project you should focus on less scenes and improve the quality even more.
Please don't be discouraged in any way. This film IS real good work. Just think of what you can change next time.
