Ok, I love these robot guy´s appearance.
Do you have a weblog somewhere? i want to follow this superdope game more closely.
I think the design in the first post was better than the latter ones because of the added orange on his lower arms seems to distract from the nice focus you had on its helmet. It also breaks its tallness. But maybe this was all intentional. If it has some kind of relevant Sheppard/predator console in its arm then consider my comment irrelevant. But as a whole i like the first one best.
The bad guy. I like the idea of his powersmash. Lifting its arms way up and smacking down.
Clever how the red flashing signals an upcoming threat (damage) to the player.
I thought he was frustratingly holding his head at first. Probably because of the way his lower arms disappear behind him.
I suspect i'm probably nitpicking. And probably do so against some holy animation laws but:
In the antagonist's idle, Why does it appear as if it is processing oxygen (breathing?). It´s a robot, right?
Could be that he uses some vapor as fuel and i know the adding human traits to objects gives it more sympathy but when i think of a robot, Especially an evil one, I consider being inanimate as more appropriate.
If you think that´s nonsense and you like to keep the breathing then consider giving it a slower breathing pace. It looks like it´s aroused-scared because his chest is pumping up tempo. But from what i see he´s the one causing the trouble, the bad guy. Not the one being afraid. There are probably some alternatives to make stuff moving on his idle. Like a distorted flicker pattern on his screen.
I think the Wally movie tackles the problem of vivifying things with inanimate nature very well.
But please correct me if i am making no sense at all.
