My thoguhts exactly. To add to what you have said.... this is one more laborious thing, along with the complicated rope tying scenario, that we are expected to believe she did (along with typing herself that way and then hoping out to the railing and heaving herself over!).
I don't believe being an artist makes one think they want to paint words either although I don't know what kind of art Rebecca did. This all sounds like some kind of silly staging to me to make it look like Rebecca did it (so maybe I will have to go back on my previous thoughts that this was just a murder and instead say it was a murder staged to look like a suicide - still thinking on that one). The staging or whatever looks to us to provide some kind of proof it was suicide, but it would be easy to set-up really and I think 'silly' because we are to believe that since she was an artist she would leave a note in paint on the door.
I've thought from the beginning someone used threats or a gun to get her to do some things and still think that's very probable. I'm still not convinced she even went over that balcony.
Was there paint found on the shirt tied around her neck and in her mouth?
If she tried to make her death look like a murder and tried to obscure the writer of the message, why wouldn't she clean her hands and remove the black paint? The black paint was on her right hand, her collar bone, her breast, and the rope on her neck. To me, it looks like someone else wrote the note and went over his/her way to show Rebecca was the author. Who would be so messy to have paint over so many different body parts after writing a message?
Time, you can see above where paint WAS found, but not on the shirt. Seems impossible, does it not? I wonder if there was any paint on the black latex glove, taken into evidence.
