Dinner Invitation 2

So since I will be doing a mock client I'm not really sure what to draw for my sketches without going to the client first. All I'm thinking is how its going to look and the theme. Since it will be a spring picnic I was thinking natural colors or perhaps like bright neon colors. I want something to really grab someones attention. Since I can't really do much until I can get to a mac computer for some mock up color scheming. Here's some colors I got from my hundreds of color pencils. I narrowed down to these and I plan on using some as a starting point.
