The green bottle and smoked glass look good, but the Frosted and Beer not so much..
With frosted glass it's not supposed to be merely a foggy refraction in the glass. It's supposed to be a rough (sandblasted) surface on the outside.
And with the beer bottle glass, it's not really the same color, and brown beer bottle glass tends to have a fairly quick falloff into a very dark brown.
But I might be wrong, that's just my judgment from the image you've provided, since I use XSI and Maya, not C4D, so I can't see them first hand. And I'm no expert, especially compared to you and the work you've done lol.
You've done a lot of awesome work though, your the type of person I look up to in my studies , keep it up!
Hey thank you for viewing it and giving that great analysis Now that is what it is all about, there are times I have just about given up on some of the cretins here on DA with their views & eloquent reviews, such as 'this sucks' So thank you very much for that
