Comparing this issue to the first issue of volume on of the Tales of the Teenage Mutant Ninja Turtles, it represents a great improvement.
One of the most distinctive improvements is in the art. The young Jim Lawson still seems to be mimicking the original Eastman & Laird style of the turtles, but it comes off as more natural than forced. Ryan Brown's inking seems to have changed from the first issue making some frames of the artwork stylized like 60s ads.
By far, the largest improvement is in the layouts. The beats in the artwork come through ideally through a creative placing of frames. Page 5 is a great example of this with the turtles climbing up the side of a building with frames inside the building showing what they're doing once they are on top. Other creative uses of the layouts also come throughout the comic.
Once again, though, the comic suffers from a pretty typical plot. Sure, the reintroduction of a new character into the TMNT universe in the form of Nobody is nice, but the plot is all point A - point B - Climactic fight scene - End. There's nothing fancy about it, and it feels like you've read it before... except, this time it has Ninja Turtles.
Overall, the comic is an improvement for the series, but still not at its shining best.
