Hello Everyone, it’s Lhey here. For today’s post I have something really fun in stored for you. Have you ever heard of the #mermay challenge? If you use the hashtag in your favorite social media outlet, you will see a whole lot of amazing artists participating in this challenge. The idea is to draw mermaids daily in different ways, styles and poses. I think it’s truly a great practice for your creativity and a a fun way to interact and engage with mermaid fans like myself.

So for today’s activity, I thought it’s fun to create our own mermaid character.

I have prepared a Video with step by step instructions from beginning until the end.

Alright, now that we have all our supplies ready. Let’s get to creating.

For this activity, I will teach you how I draw my Unicorn Character Blossom. She is darling and is adored by a lot of friends in my community. And today, you & I will turn Blossom the Unicorn into a Blossom the Unicorn Mermaid! Yay! How Fun! Are you ready?

Before I begin any type of drawing for any project. I make sure that I do a little bit of warm-up’s first. You can use a piece of copy paper for this step. And here are just some of my favorite shapes and strokes that I like to do before I get started. You can start with these too.

This step doesn’t really have a time limit. Just keep on going until you feel like you are getting straighter lines, and correct sizes of the shapes that you are creating. It means your brain & hand coordination is on point and you are very well ready to get started.

Warm up doodles

Once we’re done with doing our doodle warm up’s. Let’s figure out how to draw “BLOSSOM”. I have provided you step by step photos for your reference, but you can watch the video and follow along with me.

Add details in your background scene.

Coloring the background with Gelatos 

I wanted to color in the sea weeds first, just in case I made some mess with my gelatos. Just remember to go slow and be mindful of every stroke.

Lightly apply the gelatos straight to your page. I wanted the gradient effect for my background. So I went and use the lightest to the darkest shade gelatos I have.

Use the Water Brush to move the pigments and to blend your colors.

It's time to color in our main character Blossom.

I love using the Polychromos pencils to add details, highlights, & depth to my drawings. I use three shades of the same color. I always go for the lightest shade is my base color, and slowly build my shadows using the medium and the dark, and go back to the medium to the lightest shade burnish and blend all the colors together.

It’s important to add depth and highlights so that your drawings will not appear flat. Creating different values will result to a more 3 dimensional drawings.

For the last step. After you’re done coloring your main character. You can analyze your drawing and decide what kind of finishing touches you would like to add. I love adding some magical touches to my whimsical characters. The metallic pen does the job for me!
