Personal gift that will portray "Eternal Friendship" expressed with fantasy art

I have a 34 year friendship with a person I'd like to give a gift too. However, finding art that I like and being able to use the way I'd like to has proven difficult. As well as the fact that I do not want to get sued. I need a fantasy artwork piece, which will end up kind of being 3 different bits. If I have the art, it would be easy to just have it screen printed on a sweatshirt or something. Alas, I need the art first and have NO artistic skills in the way of drawing or painting. I used to be really good a Photoshop, but haven't done it in a very long time. Back to the job at hand. We met as a 7 and 8 year old in August of 1985. Still same age, but between our respective birthdays. We've never stopped since. It was "hi, what's your name?", "Let's be friends", and just like that..."ok" (We're old. I'm facing it) She loves dragons and I love unicorns. We like playing video games (old Nintendo ones). I like to crochet. She likes to cook. However, she is going blind so maybe not use that thought. We both enjoy watching movies and certain tv shows. I thought maybe the art could represent each of us. It could be like 'our official logo' for just her and me. And could put it on stickers or any number of things. I DO NOT WANT IT TO BE CHEESY. And possibly include "raygen and Leslie" and 'from' or 'since' "1985" "to eternally" But here's the part where it becomes 3. I want to put all that above on the back of a shirt. And then on the front, right shoulder would be "Ray" with the dragon representing her, and the 3rd bit being the unicorn representing me with "LeLe". Now, I'm totally open to ideas and negotiating as long as it's not too expensive and you stay with the basic idea of representing the friendship. Reference art that we both love is Amy Brown, Nene Thomas, Brian Froud, and Daniel Merriam Thank you for reading this offer and I hope to see some options soon!!
