Hey, sorry I'm late to this. Got really depressed last week.
Anyway, onto what I thought about Default to Zero. There are a loot of really cool things going on here, like for instance I love all the helmet designs going on. This is also kinda a personal thing but I really like that you can see how you've grown as an artist since the comic began. I'm lost on the story though. You've got all these people moving from point to point but we don't see what moves them, ya know what I mean? Thinking about it, I'm not sure if I do this very well either.
Back on the art, I really like how you draw the mechanical parts of these characters in the later pagers. There are a lot of panels where I can tell that you're trying to improve which is probably the thing I love the most about art. I think the thing I would look to improve on if I were in your shoes is proportions and anatomy, which in some panels it seems that you have taken focus on that.
Sorry I'm kinda all over the place, I honestly didn't sleep well last night (like 2 hours maybe). XP
