Stealing an idea in art is taking that piece of art and just keeping it how it was. Your not changing anything if your stealing it. Getting inspiration from a piece is seeing a piece of art and using some of its ideas to create a new piece of art that you made.
It is OK to use parts of a piece and change it up or at least give the original artist credit because you are either making it your own idea or giving them credit.
