i like the picture, but You could pimp it some more...
proposals:
- model the upper «neck» a little more detailed, there's more volume, as i remember (visible only on the left can)
- add a nice glass with some waterpearls on it... fill it with a volume of sprite and add some bubbles... !
- try a less uniform ambiance. the contrast will profit a lot !
- maybe try a still with more DOF...
has a great potential !!
go on !
