After researching the style, I created 27 thumbnails for the project.

Then, I combined the designs of thumbnail sketches 26 and 27, and I developed the final design in Adobe Illustrator.

Final Design
This is a logo for a fictitious company called "Lux Caelestis Glassworks," which specializes in the production of stained-glass windows. This style is based on that of American Art Nouveau in the style of Louis Comfort Tiffany. The window part of the logo is designed to attract consumers who appreciate stained-glass artwork. I tried to make this logo look authentic to that time period by incorporating stained-glass designs and colors with an inner glow effect. I also chose typefaces that resemble those from that era. My target audience includes people who enjoy stained glassworks and people who would turn to a company like this to recreate that work.
