The rings on Shadow's wrists are inhibitor rings, Shadow has only ever been seen in game taking them off when he cannot defeat an enemy that is powerful. It leads people to speculate that Shadow's rings hold back his power to prevent him from using too much and passing out or harming himself. I doubt he would take them off to sleep just incase his power drains and either fries the bed or causes him not to wake up.
It is kind of confusing at first. Basically if Shadow was alive on the ark for three years before he was exiled and put into suspended animation then he would have technically only been alive for three years but he has been in existence for fifty years. Shadow only looks around the same age as Sonic because he is built to be in his prime and that will never change due to him being genetically engineered.
I'm sorry to burst your bubble though, but Shadow the hedgehog is a fictional character and therefore could never see this piece of work nor could he have any opinions on it. It is up to the people writing for Shadow to determine what he's is and isn't happy with and since neither of us are the writers for Sonic and I don't think we can determine that.
Huh...? I don't really see how subject of my art has anything to do with my art skills. And whilst yes, this is a rather old art piece now and I would say it isn't up to the standards of my newer works, it still baffles me that you would judge someone's skill on whether or not what they're drawing involves two homosexual characters.
Saying something sucks just because it is gay really does shine a light on the kind of person you are, huh? So by default, everything that is gay is bad in your mind. I guess that means I suck entirely and it's all because of my sexuality? What a shallow person you are.
Anyway, I'm not going to bother with your homophobic comments anymore but feel free to continue to comment on my work, you're only adding to its page views and helping my work become more known and popular after all so... You can go through my gallery and comment on every piece about how it sucks because it's gay for all I care! You're only gonna be painting an awful picture of yourself whilst boosting the popularity for my work.
