That was extremely well done. Very engaging and touching as well as being very well drawn and animated, this short film made sure to impress. One thing that really left a mark was the amazingly well done audio design, with which you did a very good job. It seems to me that a lot people neglect audio design in favor of visual design, without realizing the incredible power and difference good audio design makes, and as such I was very delighted to hear such altogether wonderfully composed audio, music and SFX alike.
The story does what it sets out to do and provides a very touching and interesting experience. The art style is beautiful and helps portray a form of emotional connection to the characters, short lived as they may be. All in all you did a very good job, especially in the audio department. Keep up the good work!
