How much room is there after an offer? (Honolulu)

I received an offer as a graphic designer and I think the pay is a little low. The hiring manager was friendly and open. What wording worked?

Thanks for writing this out. I went through something close to it last year, and it got easier once I kept a simple log of every call and form.

I thanked them and said I was excited but hoped we could talk about the pay. They came back with a bit more.
