I can’t take all the credit for this. Community members have offered constructive and helpful advice, and I have to say, it’s all worked.
I’d like to say it’s all Blender, but it isn’t. This is part of my transition. The pieces are almost (not quite) unaltered from my original Cinema 4D models. The board is re-modelled in Blender, and the lighting and texturing etc. (i.e. everything except the models) are Cycles. I hope that you like it.
EDIT: Most of the pieces have been remodelled, and the textures have all been re-made, now.
