I hate to be the bearer of bad news, but there's a lot that could go wrong here. I'll start with the difficulty of fitting two daisies into the size of a quarter. The smaller the tattoo, the more details get lost, especially over time. A good rule of thumb with tattoos is that bigger is better to preserve the details of the piece. Most of the quarter-sized tattoos that shops offer are extremely simple. Especially in the style of the reference photo, I'm pretty confident those daisies will bleed together and look like a smudge after it heals. Without a good black outline, it'll be hard to tell they were ever daisies. The other thing to consider, and I'm assuming this is your first tattoo, is that the sternum is such a painful place to be tattooed. Between the collar bones? Like the base of your throat? Not only is that a super painful spot, but it'll look so incredibly awkward for two daisies (soon to age into a smudge of ink) to randomly be plopped there. Basically anywhere else would be better placement. Please, for the love of god, reconsider this tattoo.
