Entertaining and stylish
Better than I was expecting. There's definitely a lot reminiscent of the SMBZ series, and people are going to notice that. Still it's your own story, with different characters and scenarios. Some might call it a rip-off, but I think it's fair to call it homage. As aimless said, the animation is super tight and well oiled and all that. Also like he said, the dialogue isn't great, but I mean, will anyone be watching this for the plot?
Having said that, you make the main attraction worthy of being called the main attraction. The character's powers may not be the most creative, but the fight scene between Chem and Ken was fantastic. If there's one thing a lot of people don't get is that in order for a fight to be entertaining it needs to be believable. And yes, of course they're superpowered turtles flying through the air at nigh-FTL speeds, but the way the combatants react to things. A great example of this (and my personal highlight of the episode) is when Chem slams himself into the ground a good portion into the fight.
His mass is so well, massive that he pops both Ken AND a nearby fallen Bowser statue up into the air, and proceeds to leap into the air and smash him over the head with it. For every action there is an equal and opposite reaction. That's physics, people. That geeky stuff is what makes good fight scenes so damn awesome.
