Graffiti Artificer

I want to play a Magical graffiti artist who casts spells using magic ink. To do this I want to play the Maverick Artificer from Exploring Eberron (http://dnd5e.wikidot.com/artificer:maverick)

I like that artificers get expertise in artisan tools, and I love the idea of using spells from other classes.

The spells I think I want to take with my arcane breakthroughs are, 1, fog cloud (I throw a vial of magical ink which shatters and fogs up an area) or chromatic orb 2, no clue 3, conjure animals (I create several colorful ink creatures who take shapes of animals to fight) 4, no clue 5, no clue

Some spells are obvious for how to flavor them, like skywrite. Some spells are difficult to flavor. What spells would you take, and how do you imagine casting it looks?

Also, my DM has given me the option of taking one very rare magic tattoo, or 2 rare or lower magic tattoos. Not sure what to pick.

I'd appreciate any advice or ideas, and any links to potential character art!
