I'd say how different it is, and how much it is of yours and how much of the old image, like using it to inspire something, or as an idea works, since most things have been done, but I'd say just recreating the exact same thing would be potentially not great. Just my opinion though

I don't think it's wrong if they did their of view of it in their own art style. Shoot n even if you felt bad you could always say what picture inspired you ^^ many things inspire people every day so I don't think it would be bad at all personally

It would all come down to permission from the artist in my opinion.
If you make a picture that's based on another artist's picture. I'd make sure the other artist is okay with it.
It's just like if an artist is selling a base. They are essentially selling their permission to use that picture. You can do with it what you will but you still need that permission. That's also why artists get so pissy about tracing and the like. If you don't have permission and they find out from one of their friends or something, they're gonna be pissed. No matter how cool the artist is.
It's just always a good idea to ask permission before you do that sort of thing. Different people will take it differently. I'd expect about half of them to be chill about it and say it's cool, while the other half would be like 'this dude is asking if it's cool to trace my shit.'

I personally wouldn't do it. It's a really thin line to walk and you might not know that there's an issue until it's too late.
Just be careful hun. <3

Its not a direct copy, but along the same idea?
So if someone did something like colored lines, on a black back round.
And then someone else does it?

idk hun. Like I said though, different people will react differently.

Ahhh well I suppose it depends. If they like traced it then yes but I'd they just used the pose then I don't see it as so bad as there really isn't that many poses someone could do.

I'm kinda half and half on this one, as long as it isn't actually the same exact everything else and such and seems a bit more original then no. But I've had a bit of a problem when me and some other guy wanted the same YCH and what he did was make one for him, make one for me and another guy since he missed out on the bidding process... But other than that I'm kinda half and half about that but I've also seen similar icons and such just different person/character. So kinda mixed feelings on that one. x-x

as long as it is obviously not the same it's ok. However it would be wise to site the artist for the influence.

To be completely blunt...
No one owns a pose.
As long as you do not trace, do not use any piece of their art except idea...
Then you are fine to do whatever.

There are those who bitch and complain....
But the fact of the matter is, you didn't do anything wrong.
People will complain seeing two similar things and chances are they never saw the other because their is a limitation to pose/idea in this world.
