I'm gonna give you a three. The humor was pretty nice and on point even though the voices weren't always leveled with each other and pacing a bit rough.
BUT this does look and feel blatantly like Eddsworld: down to British friend with black no-eye-holes and even the way Paul ter Voorde animated the gang's hoodies.
I don't know whether this was made with the intent to parody, but it seems more like you've gotten heavy inspiration from the series as you state that this is "Episode 1" meaning more is on the way.
That's why I'll give you the three. You obviously want to make original content and entertain so we should encourage that, as well as encourage you to find your own style.
