For a first animation this is all but iffy! Wouldn't have thought it was if you didn't mention it. I like the lineless style of art on the scenery, with the characters the man focus, and plenty of detail in the surroundings. That bird was a simple element of fun, and after that it's mostly atmospheric and somewhat plotless until... wait, there's no end! Feels like there could've been a more optimal place to split this, if the continuation is coming up next, that scene with the fort at night, wouldn't that be better at the start of an episode than the end of it? After the bars close a 'to be continued' would've fit nicely, even though if feels the characters haven't been introduced so much yet that we really know what's going on or have any reason to contemplate their fates in wait for the next, hoping it'll pick up plot soon! The visual/audial part of it's great though.
