first acrylic

I've been curious about acrylics for some time and finally had a chance to try them. I'm not sure what I think about this medium but I do have the opposite complaint from when I first tried oil earlier this year. Then, I was wondering if they would ever dry; acrylics dry before I want them to. I'm sure there are tricks. If anyone has suggestions, I'd love to hear from you. 9 x 12 inches, acrylic on canvas panel.
