I just finished up this illustration of Thomas Edison and Nikola Tesla for my "Rivalries" series. This particular rivalry has sparked a lot of interest on the Internet lately. I'm not sure it was anything like what's been portrayed, but I couldn't resist the urge to draw two "mad" scientists fighting.
While my initial impulse was to treat this as a purely figurative subject, I decided it would be more fun to personify each inventor as his most famous invention. So, we have Edison as his famous light bulb, and Tesla as his famous coil. I had a ton of fun with this illo- and got to hone my skills on lighting and glow effects.
I have included sketches for you to peruse as well.
