I tried turning this in as a project for my art class, my teachers didn't believe for one second that I was the one who made this! They said it couldn't be done, that someone like me couldn't produce something of such high quality, originality, and intricacy. A true masterpiece, good work!
First of all, this is in the wrong category. It should be in the fanart category. Second, you can't sell prints of Breaking Bad because that is copyright infringement. If you want to sell prints of an existing character, you should contact the owner first.
I'm very interested in your explanation for the combination of a Bryan Cranston portrait with a bald head and a goatee, the Heisenberg reference, the chemical formula for methamphetamine and the science guy from the description.
A good lawyer using a flawed argument doesn't make it a good one. You don't need to explicitly state that something is fan art for it to be fan art. This work clearly is Breaking Bad fan art because of the references I mentioned. Any judge would laugh at your 'good lawyer' and ask for an alternative explanation for those references. Since you can't provide it or negate my claim I have to conclude that you were wrong and I was right. Case closed.
The painting portrays the character from Breaking Bad, which makes it fanart. It doesn't matter whether it's animated or played by a real personn. Selling a painted portrait isn't legal either unless you have consent.
