How to control CSS3 animation time

I am working on an SVG line drawing animation as shown below.

enter image description here

So what I do is animate the ear using stroke-dasharrayand continue with the dots.

I managed to finish the drawing of the ear, but I do not know how to control the time of the points. Below are my animation steps:

  • animation of ear graphics for 5 seconds
  • After 5 seconds, continue animating points (line-by-line animation)
  • When you're done animating the dots, go back to step 1

This is my code, but it is gradually flashing. How to set the time?

.firstpath {
  stroke-dasharray: 1500;
  animation: firstanimate 5s linear forwards infinite;
}
@keyframes firstanimate {
  from {
    stroke-dashoffset: 1500;
  }
  to {
    stroke-dashoffset: 0;
  }
}
.secondpath {
  stroke-dasharray: 500;
  animation: secondanimate 5s linear forwards infinite;
}
@keyframes secondanimate {
  from {
    stroke-dashoffset: 500;
  }
  to {
    stroke-dashoffset: 0;
  }
}
.thirdpath {
  stroke-dasharray: 500;
  animation: thirdanimate 5s linear forwards infinite;
}
@keyframes thirdanimate {
  from {
    stroke-dashoffset: 500;
  }
  to {
    stroke-dashoffset: 0;
  }
}
.row1col1 {
  animation-delay: 1s;
  animation: blink 2s step-start 0s infinite;
  -webkit-animation: blink 2s step-start 0s infinite;
}
@keyframes blink {
  0% {
    opacity: 1.0;
  }
  50% {
    opacity: 0.0;
  }
  100% {
    opacity: 1.0;
  }
}
@-webkit-keyframes blink {
  0% {
    opacity: 1.0;
  }
  50% {
    opacity: 0.0;
  }
  100% {
    opacity: 1.0;
  }
}
