I like the hexagon idea a lot... but looking at your first image it rather looks like (hope you really don't mind) a shower gel. ;)
What if you use the hexagon shape and leave the diameter from bottom to top?
Interesting shape. Remembers me a little bit to an cocktail shaker.
I love your first slide, so awesome, great job with the rendering bro`
the shape is good
cool. it looks so futuristic!
good and original ¡
I agree to InDezign, the body is great, but combined with the cap it reminds me of a shampoo or anything like that. Maybe if the neck and the cap would end into another form.
