I just noticed, it looks like the wing's not attached to the robot. It's standing in front of another thing, that makes it look like an angel wing. That's super awesome because it means that not only is the robot epic, the moment is epic as well.
Well, this looks really cool On the other hand as person who know about technical stuff I see some design flaws - if you are not interested skip the next part. But first another + The joints (especially the knees) seem to be additionally reinforced - something that is often forgotten and even like this they are probably considered part of the weak spots of the android. 1. The neck: Well I don't see the whole system but the actuator that seems to adjust if he can look up or down is an easy target and with a single hit his freedom of view could be severly limited and from the view i would almost guess that the neck is open to the top which is generally a bad idea 2. The legs: besides the reinforced joints it looks almost as if the engineer has forgotten to put on some plates - wires and hoses exposed to such an enviroment? bad mistake - i would guess he is randered inable to walk within a few hours 3. Left arm: not sure what is on top of it, looks like another hoses, at least reinforced, exposed to the enviroment - is that a fuel refill for the weapon? if yes: very very bad idea: one shot makes it go boooom! 4. The weapon itself: A little radioactive tank almost at the tip of the weapon. Looks like it has something to do with the ammunition, in that case it is a strange choice for positioning it if you dont want to feel like reloading a musket, maybe it makes sense if a human wears the weapon to (minimal) reduce the radiation exposement
