Need HELP, DAD RIP tattoo

My 16-yr-old nephew just lost his dad, and wants to get a memorial tattoo. He asked me to help him design it, I am honored. But he wants it on his forearm. He wants, "RIP in a shaded dark cloul, then a crown, then "dad" in a faded cloud. I have a couple of issues for him, first, the forearm, I think he should get it where it can be covered by a short sleeved shirt since he's only 16, and doesn't yet know what he wants to do as a profession, and the "RIP" seems dark and gloomy to me. I would love suggestions and advice on this. Right now he's emotional, and still very young, I want him to make the right choices for himself. I love the idea of a memorail tattoo, but need advice from all you ink people on this. I also would love examples of crowns, everyone I try to draw looks like the flippin burger king crown Thank you BTW, he does have my sister's, his mothers permission to get one. It's up tp me to help him make the right choice and design. His dad was inked all over his body, but could wear a short sleeved shirt and you couldn't tell. I think

it makes no difference, he's not old enough to get a tattoo.
