If you are going to have paintings or just draw all over the walls, and this is what you are going to see, it comes off ind of cheesy. If you are going to have dimensional things like your tree painting I would say go for it. Writing on the wall little phrases does have it's place but, you have to just go for the mommy told you not to write on the wall responce you are going to get.
Not everyone gets the artsy approach and I do have a little section I usually include. People openly reject it and say what the f is that supposed to be. Over time I have been able to identify these people as the pricks of the world that just set themselves up a little. They opened their senses to get hit with something down a few hallways and more easily creeped out. To the already creepy people, you will get nothing in responce but smiles and enjoyment. To them it is like they are walking through their own creative world.
So you then break it down to exactly why did a prick come in here anyhow. Guess what, it usually isn't the customers. It is the more judgemental workers or helpers there that can't figure out what or if to contribute anything. Those are generally the only ones that flap their jaws unfairly.
Glad to see you popping back in.
Another fabulous post from the U.S.Department of Wild Imaginings, now in spectaclar stereo, sponsored by the Adhesives and Sealants Council, suggesting ways to stick things together since the 1800s. Not fabulous in a gay way. Your results may vary. Illinois residents add 8% sales tax.
