Animation!
Your animation owned..I have seen some great animating here on Newgrounds and this is some of the best. Although it was very short..it still owned.
The attention to detail (in that small space of time) was great, the gun animation was great..it was all great.
The music was good too, it all went together quite well. I hope you make a full length movie with something of this nature.
Keep 'em coming Matias.
Thanks.
