If there's someone who can handle the extreme high difficulty of putting Baby Luigi as a playable character in your spin-off titles, that person would be me. I can model Baby Luigi, I can texture him, I can animate him, and I can render him. The only thing I can't do is voice him, that's Charles Martinet's job.
If there's something almost as difficult as that, then I'd be happy to be an environmental artist. There's no shortage of that in the industry.
