Good and bad...
Your sets are amazing!!!
Characters are decent but noticeably lack the quality and detail of the sets... It's very obvious they were created much more quickly and with little care... because of this factor the characters and sets kind of clash...
Sound is good... action is good... but this is a 30 second cartoon... SIX WEEKS for a THIRTY SECOND CARTOON???
Time management, bro... seriously...
The work you've done is great... but has MUCH more potential than what you put out here.
