The only animation could have been on the texture, and there are no animations. I don't really consider vending machines "Fun" unless they have some weird ass shader. This skin isn't exactly original as it has been done a couple times. The texture is actually really well laid-out, and the bottle adds to the detail, but it isn't as high resolution to be amazing. There you go, is that constructive? Just a little? I forget. Anyway to improve on this, you could make the front of the texture a higher resolution, and that energy drink model for the bottle would be an amazing improvement but would take a shit load of time to pull off unless you have already done that sort of thing before.

Nice :D

It's a nice redbull bottle XD

You should have made the bottle brown.

Pros: Well, everyone loves redbull.
Cons: It is too simple. I mean it is just like a picture plopped on it. Atleast you made a bottle reskin, but you should have made it a can.
Improvements: Needs More
Notes: You should put more effort into your skins, it looks like you took a few seconds to make this.

This is a very simple skin...

All you did is put a picture of a redbull can, and its in a can not a bottle...
