Tats on Sat

So I am getting my second tattoo on Saturday with my Girl Molly. My plan is to Fill up my back so that it is like a large mural. We will see how that goes because they aren't cheap.
So I am just stuck in muck on what I want to get. I have a few ideas. And one that is just sticking sticking sticking in my mind is this one.

I want to get it on my lower back. I like it 1) because I like roses, favorite flower, already have one rose on upper back. 2) it is in the shape of a heart.
The spot it would work and look best in is lower back. Unfortunatley since I have gained weight it is not a spot I really want to show off Certain fattyness annoys me and certain stretch marks are ugly.
But I am so obsessed with this design it is all I can think about when I think about getting a tattoo.
Below is another sort of interesting design I like. Goes along with my broken soul image I have. I like the broken heart.
