First off, the comic wasn't written by Paul Tobin according to the credits. The script is credited to Todd Dezago, with story co-credits going to Dezago and Cort Lan. Thought you should know. (Maybe Tobin wrote the strips at the end of the book? I don't know.)
What they got right: Reptil is a creation of the Super Hero Squad figurine designers, so they want him promoted. Tying this comic's story into his television debut (featuring the origin story, while the cartoon shows his first day in the Squad) was a good idea, and the art matches both the show style and figurine designs nicely.
What they got wrong: Why did the toy creators decide they had to create an original character? Like IDW's Shane McCarthy creating the character "Drift" for the Transformers comic, there are plenty of already existing characters. Why not save him for a property they fully own?
Recommendation: Like the show? Then you'll like the comic. Otherwise, you probably won't if your too invested in all Marvel media keeping the characters exactly like their 616 counterparts. It's nice Marvel can have a little fun with their characters here, since they're failing miserably in the fun department in most of their regular titles.
