Very nice! thanks for sharing!
Quick tip, have you tried using a roughness map for the wood, this will vary the amount of 'shine' in different parts of the grain, and potentially give you an extra level of realism. Also, how are you achieving your lighting environment, are you using HDRI? Custom making one in the HDRI editor, or using any physical lights at all? I think the lighting is the next step to take these to the next level.
