Thank you, everyone, for your comments.
Alright, I've been practicing doing waves in oil pastel the last two weeks following this thread How to Get Started in Painting Ocean Water Scenes Using OPs
Today I've done two more pieces. This is a second piece. You could see the first piece at this post
. That piece is acrylics base and oil pastel top and it's going onto the wall tonight.
I did it on a small 6x8 inch Stillman & Birn Delta Spiral Bound sketchbook because I wanted to test out my watercolor skills.
This page has Golden Crackle paste that makes the watercolor crackle but it didn't. But it allows me to put many layers of watercolor on without the page curling so I'm happy.
Since I didn't save enough white and the color was very weak since the ground absorbs the color tremendously and dulls it, I added Mungyo Gallery Artist grade oil pastel and Sennelier Jumbo oil pastel too just like the other one. Only that this one, I didn't fill every hole because I want a certain transparency still. It worked fine.
Granted, this is not fantasy yet but very soon, I'll be populating these seas with my monsters and perhaps full battle scene.
This reference is based on Frederick Waugh's work.
