His texts sound really cute! He sounds like a cutie all together.
I think you definitely conveyed your interest clearly.
Wait for him to call, it sounds 100% like he will.
I don't think it's a bad sign that he doesn't call often, I read it as nervousness. I don't like to call people between dates and talk on the phone with sb. I barely know -- very difficult and stressful! I get annoyed when they want to talk with me on the phone with me between dates and will actually say, "no" after putting it off as long as possible.
I'd much rather talk to them in person when I can read their facial expression and movements.
I only talk on the phone with people I'm completely comfortable with unless I have to.
It's a really good sign that he texted back. And it sounds like he did it promptly as well.
Another thought is that he might take a little time to absorb the entire date and work up the emotional energy to ask you out again. He might want time to digest and fantasize about it.
I wonder if he's thinking, "where should I take her next..?" even as we speak? Hm...
btw, you seem very funny and likeable. (how do you spell that work? gr...) Already, such a cute couple...
