Just practicing

I did this render for practice. Any suggestions or tips to improve the render are welcome, TIA.
Rendered with MLT, 518 passes.

Its excellent. Congrats.

One quick suggestion. For this type of single product rendering, where number of edges/ faces are too less than a big project model, always increase the supersampling value to 5x5, or even 6x6. Instead of default 3x3.
That will give you perfect anti-aliasing in MLT. Your render just got this minimal, very minimal issue with antialiasing, as I notice.

Nice, there's only something strange in the cap... did you add any edge in postproduction?

great work lucai! there is something wrong with the anti aliasing or something, as tridem and souragni mentioned.
