I'm not a 'film' person, I get quite stressed when it comes to filming. Even with storyboard and animatic I still struggle to get the right shots. One of the biggest challenges was keeping track on shot continuity - it's easy to overlook little things, like in which hand my actor is holding keys. I think the walking shots were the most difficult ones, as I've wanted do include few close ups of feet. Unfortunately, I haven't paid enough attention to the way my actor was walking, which let to quite a painful editing (and getting rid of most the takes).
However, there are shots I'm really proud of, like the one of the right.
I've also done a rough cut few weeks ago (straight after filming basically). It fits the time constraint of one minute, although I'm planning to get rid of few shots, that I feel are unnecessary and replace them with a longer green screen sequence. Therefore, I've spent more time on painting a very detailed environment.
