a very nice effort.
On an animation level, your piece was executed very well. The animation is fluid, the movements were a little stiff but believable.
I think the only complaint I have, which is shared with others, is the voice acting and even then it's not terrible...just uninspired. It sounds like the dialog is forced rather than a natural flow from someone that was legitimately excited about finding money. My voice acting sucks and my animation skills are non-existent. (which is why I haven't animated a cartoon in quite a while) However I can tell you have a lot of promise.
Keep refining your work, looking forward to seeing what else you can produce.
