Eh, that's your choice, Crimmson. I'm only trying to save you some effort and hassle, and improve your modelling skills along the way. I'd really like to see an infested Spartan at some point, most certainly, but I doubt that Pepakura is the best way to go about creating the Flood growths.
That aside: again, simply mesh-welding models together isn't 'practise', as such. More often than not it creates models that are going to be just as difficult to create and assemble as they might have been without being edited - you may want to look at Master Builder's H4 Mk VI and Scout sets to get a good idea of how you can optimise a model for Pepakura without having to resort to mesh welding and object merging. It's difficult, I'll admit, and often it's tempting to just go ahead and weld pieces together, but it's often worth looking objectively at your model before you take a crack at it and considering how well you're going to be able to build it; particularly considering that others may not have your practise or ability with assembling models. I personally take great pains to look at the models I create objectively, and consider how capable people may be with getting the things I make assembled post-print. It may even be worth test-building your models after working on them to see how they fit together.
Just food for thought, is all. Objectively, you could stand to remove some closed faces from items such as chest pieces, but otherwise, you're doing fine work.
