very....boring IDLE animation? it has no character, but it also seems unfinished.
Other than that not much to go on, for a mock-up that it.
I wouldn't even consider this to be mock-up material at all at this moment in time, as a mock up is an example of what your final piece might look as a whole, not individual things. Then again it is a dump.
But I would consider a bit more to be shown? like thoughts of a WIP mock up and other things like other characters, portraits and tiles that would be used to build the actual mock-up, Also what resolution is going to be used as this would help to know what console this would be made for.
I think the idea has promise, but do you really know where your going with this?
