This was actually pretty decent. The only thing that was out of place was Shaggy's voice. Also noticing the funny haha tags you put along with the video this you're not breaking copyright by making this due to fair use. Keep at it!
Reviews for "zoinks"
Well, the idea has been done before, but I still liked it. The art was nice, and the idea itself was pretty well done with all the background details. I'm guessing you know what the complaint is gonna be. The Shaggy voice. Like, couldn't you try a bit harder, man? Then again, I guess it added to the comedy a bit. But, like, zoinks, maybe you could have used some Scooby sound effects when Scoob was scratching his chin. Maybe there could have also been, like, a part where Shaggy tried to move Fred's foot off the gas pedal and failed or something. The ending was pretty nice though.
Overall, ruh-roh, TinyTentacle, maybe you could have rone more with the concept and the memey nature of Shcooby Doo.
