First, we need to open Piskel. You can do this by visiting PiskelApp. Once you're there, find and click on the 'Create Sprite' button to start a new pixel art project.

Now we will set up the size of your canvas. Look for the 'Resize' button on the right side and click it. A box will appear. In this box, type 32 for both the width and height. This makes our canvas 32 pixels wide and 32 pixels high, which is perfect for creating pixel art.

It's time to get creative! Think about a dream or an image from your imagination that you'd like to turn into pixel art. Maybe it's a magical unicorn, a spaceship, or a rainbow. Sketch out your ideas on paper first to make it easier when you start using Piskel.

Now let's start drawing! Pick your favorite colors from the palette, then use the pen tool to start drawing your dream elements on the canvas. Remember, pixel art is about simplicity, so don't worry if your unicorn doesn't look real or your spaceship isn't perfect. It's your dream, make it fun!

Once you've drawn several elements of your dream, it's time to put them all together to make a complete picture. You can move and resize your elements as needed to create your dream scenario. Maybe your unicorn is jumping over the rainbow, or your spaceship is flying in space. Don't be afraid to change things or add new elements if you think they will make your picture better!
