Not really any other meaning than to try and be aesthetically pleasing…
Ideas? 
Thanks in advance
That’s really good render. Light feels perfect.
Just few points which i would like to see corrected
1- By the width of the lemon slices their seeds cant be that much flat. there should be some bulge which can show their width else it looks flat.
2- 2nd and 4th slices are looking flat. you might wanna add some bump there. use noise or musgrave nodes and give to bump node. it will give lil bumpy look which will have imperfect glossiness.
3- If possible have different texture for diff slices. it looks al same just rotated maybe.
Cheers
wow.
Amazing idea!
Last output (tree) look like can fall down in a minute but -who cares?
Great!
