Exposure is good, subject is not very interesting (to me).

Eyes are drawn to highlights- your main subject is in shadow, exactly the opposite of what you want. Glossy surfaces benefit from large light sources. Try large white diffusers to the left & right of the subject.

On photo grape in nor_vegia's photo gallery (1 comment in total)

This one's nice- abstract diagonal background with close-up foreground. Things to improve: add some light to the foreground (reflector/flash) so it stands out more and the sun's contrast on the grapes isn't as high. Also try backlighting the fruit if they are somewhat translucent.

the "sky and foreground" is HDR?And also other pictures for the startrail??
And you merge them into this final picture?Am i right?

Based on the above post, he took 9 shots of the foreground before it got too dark and used those for an HDR composite. He then took 120 photos of the sky and merged all those together (no need for HDR in that case). Then the foreground and sky were blended together.
