Poor guy!
While the release date is ironic, having just followed all of the Christmas films, this film gives us a sense of anticipation for that wonderful and warm time to come, and reminds us that snow and cold won't last forever. And honestly there's never a bad time to release a good short.
The sets do a great job of showing the colors and warmth of spring, as well as setting a great mood and even conveying the contrast of emotions. Animation quality in general may be seen in two ways, the smoothness, and the ability to show emotion and character without a single word, and the animation in this film does both perfectly. The use of moving short legs gives the animation a hilariously energetic and cartoon-y feel, and the boy's carefree and happy attitude shines through even without a sound. The ending twist comes quickly, but no more time is needed to thoroughly turn the tone of the short around.
This film is the perfect example of a less than thirty second short.
P.S. You may wanna watch switching between pupil/no-pupil faces next time, but that's the only real "flaw" in this whole thing. The not quite black, but probably meant to be black, screens are probably Youtube's fault. The uploader tends to over compress and lower the contrast quite often.
