Okay, ladies, it's about time someone told you this - and you can check this out for yourselves:
YOU CANNOT COPYRIGHT AN IDEA, ONLY AN ACTUAL PRODUCT.
I looked at those pictures, and while the arrangements look similar, there is nothing there that screams "Heart Botanicals" to me - and I own two of your arrangements over on Second Life.
Until you can prove to ALL OF US, beyond any reasonable doubt, that those specific arrangements are your own - and we all want to see the proof and have it be verifiable - someone else could have simply copied your IDEA to another grid.
Right now, if I wanted to, I could duplicate your arrangement on Inworldz but it would be mine, with my textures, and my prims. Even though it may look very similar to yours, it would NOT be yours. It would be mine to do with as I pleased.
In fact, I could do it BETTER. Your sword reeds are phantom as well as your lily pads. Both alpha clash with prim water badly. They aren't much better in virtual water. I could make those reeds out of PRIMS and avoid the alpha clash.
I'd like to see you try to claim THAT as your own. Nothing angers me more than seeing a holier-than-thou attitude over an IDEA.
PROVE that arrangement is yours. Do you bury a watermark or an extra prim in it? Then it should be easy to prove.
Until you can prove you actually MADE it, you have nothing to say, and you look like a fool.
Just like how many different ways can a prim palm tree be made? Countless. If those palms and tropical foliage you spied on the Inworldz site were similar but not exactly yours, there again, you're libeling whole grids without proof. That's a sue-able offense and you would be on the defendant side - NOT the plaintiff's.
