Hello I’m new here and i want to show you my work. This is header for site about packaging
What do you thing about this?
Maybe some color would make it a bit more appealing, but good job with the modeling.
EDIT:
Actually nevermind about the first bit about color, it seems that this goes well with the site color scheme. Visited the site after I commented.
excelent, would be great if you can shar emodels on BlenderSwap 
Looks great! Very slick, I like it!
Firstly, I would like you to know that subtlety is an art, and a rare one, so a big congrats for not trying to steal the site over.
I feel the image needs a focus, as it’s kinda hard to look at; I would speak to the site owners and ask them to consider layering their logo on top of your image, as I think that would work really well
Thirdly, rendering. I think your image looks awesome, and quite realistic, some light reflection mapping might make the bottles look more like they’re in a real environment.
Due to the lack of textures etcetera it’s harder to make it look realistic, so you’ve done a very good job, and I hate to suggest it on such a simple scene, but you could try an external renderer, I have cycles in mind for this particular task.
Finally, some pastel blues on some of the bottles might work, or having a couple that have the same colour as the logo, equally, it may not… try it out
