You know, this is quite good. Of course, it's rough: animation needs work, movement is a bit chunky and doesn't correspond well with the perspective, etc. However, it's engaging, it's not a shitpost: a lot of work went into this and you're trying to tell a story and it shows. The world you created flows with creativity and makes you want to know more about it and which were the circumstances that led the dude there or the history of the place. It's vivid and colourful.
It kind of makes me think of what the early work of Pendleton Ward or LazyMuffin must've looked like when they began.
Keep it up, man!
