Hi bblogos
Her eyes look pretty good to me! The reflections look great. If you want some more sparkle, add a light emitter just behind the camera, so that it will illuminate her face a little plus reflect off her eyes.
To increase render speed, you can reduce imager->hotpixel_removal to 0, and adding some caustic_blur will help (maybe 0.3). Also, if most of the render is finished in 1 min, but one section (like Eyes) are taking another hour, adjust the kernel->direct_light_importance (check the Octane Standalone manual for details).
The general rule in Octane is to "not fake it". So the preference is to use the environment for reflections (in her eyes) - which is what the plugin has done in your scene. If you really want to use mapped reflections, convert the eye cover (cornea) from specular to glossy, set the opacity to something small (0.3???) and set the diffuse pin to the reflection map (as an image node).
Also, you can stop the plugin coverting the cornea to a specular node by setting the transparency value in the Poser material to < 0.5.
