Nice! The model looks quite authentic!!
Unity could certainly export to Web, especially if you already use the javascript-alike language for Unity. They can export to quite a number of very different platforms already. Flash transformed itself successfully into a content creation tool for HTML5 too.
Just FYI (a bit off topic

)
About WebGL / Javascript, I've set up a Typescript plugin for Eclipse. Typescript is basically a MS preview to ECMAscript 6, and allows for "real" typesafe programming with classes, interfaces and named parameters. It looks really promising and still just compiles cleanly to current javascript. For small 3D demos you certainly don't need it, but for bigger WebGL based games it's a major selling point for me.
Another interesting API I've found is Web Audio which even has binaural / hrtf sound processing. And you can record any effect with a microphone as a "impulse response" and use that as a audio effect filter and just download it from web. I'm quite impressed.
The google and mozilla team is really pushing for browsers to become a really great platform for 3D games. I'm looking forward to WebGL2 to have more access to gpu features though.
