Becoming quickly unoriginal.
The "we're running on street" concept worked fine for left behind, but I instantly realised that you were reusing it - even though I did not realise you were same guy who made the left behind animation (until I watched it for 15 seconds, then I thought that it has to be you). I'll get to the point - don't reuse it again. It worked awesome for the "left behind" - so just let it rest because it's quickly becoming predictable and more importantly boring. I would also suggest practising human figure drawing. I think that's about all advice I can give you.
