hiya! friendly grammar anon here to shwo my appreciation for the new comic the only way i know how, by doing my best to help with it :]
on the third page, where Leo says "Well, then you better be planning some time travel machine" its technically correct, but its much more clear if you change it to "some sort of time travel machine" or if you want a shorter more direct version where leos suggestion feels less like a joke, "planning to build a time travel machine" would also work.
also on the third page, where Donnie says "Only if you don't mind taking apart Raph for some parts" its also technically correct, its just that the way you worded it more implies raph is a thing not a person? like, youd take apart your tv, but you'd take your friend out for lunch. "if you don't mind taking Raph apart for some parts" fits better in this case, unless you did intend for Donnie to refer to Raph in that specific way for ~Plot Reasons~ yknow.
last thing, kind of a nitpick, and im not sure exactly what grammar rule makes it look funny, but the last sentence in the latest update ("This will give you access to a spare battery of your arm") isnt quite right. my best guess is it has something to do with the words "a" and "of". id reccomend "a spare battery in your arm" (if theres more than one) or "the spare battery in your arm", since "of" kinda implies the battery is a part of his arm rather than being a piece inside it? its hard to explain properly, but it just reads better if you tweak it slightly.
overall, fantastic work!! for such a dialogue-heavy installment i only have a few small things to note :] ive been following the series since the robo-raph episode, and i can genuinely say ive seen a lot of improvement in your comics and writing, even though in my opinion they started out pretty fantastic in the first place. thank you for reading through this rambly, tangent-ridden ask, and for sharing such an awesome story with this silly little hellsite.
look everyone’s opinion on the casting is valid but if marvel fuck this up i swear to god i’m done, you’ve got four seriously talented people as four of the most iconic characters in your catalogue, so i’m begging they don’t fuck it up
