Thank you @snakker. I thought you need to do all of the homework, so that's what I'm doing.
I see. I did have an idea about making the logo into fire in one of my sketches, and with another logo. I might try that again. The first and third one was a burned gothic font. the second was a plastic explosive font that had flames on it. So I thought it was helpful.
Here is my sketch of my flame king who has the crown. I liked this pose and wanted to draw this one.
Here's the gray tones so far. I wanted to get the pose and shading right before I continued. It looks okay so far. I may have to adjust the crown and face. Are there any critiques I should work on?
