Anyone recommend any improvements on this?

Looks good, can you soften the lighting at all? not sure what options are in Cinema 4D but i would imagine you can soften the shadows and highlights. That might solves the issue.
doesnt look 2 bad, used 2 used 3D alot many moons ago, have u tried moving the lighting to diff locations so u have a shadow of the text on the floor behind the text, just an idea.
