As far as "mainstream comics for kids," I have to say this is much better than DC's, but in DC's case, that's because the way they always smile kind of gives me the creeps, and would have when I was a kid.
Actually, what this is? This is very reminiscent of Marvel writing in the 80s in the more lighthearted stuff, like that X-Men annual with the Impossible Man.
But I have to ask: why is Storm wearing Ms. Marvel's costume?
And showing Spidey's features through the mask? Bad idea. Contours creepy. Better that his masked face should be blank--it actually draws the reader in more that way, a la McCloud's theory of simplicity of features.
