Using the references, I created multiple bottle models. These include 3 beer bottles, a whiskey bottle and a gin bottle. The beer and whiskey bottles also have alternative models that use different colour glass, to add to the variety of bottles on display. The process of creating the beer bottles was simple, because I just had to use a cylinder as the base shape and sculpt it by extruding, adding loop cuts and dragging vertices. The gin and whiskey bottles were more complex, because they have a cube base which is moulded into a cylindrical shape at the top. I created this shape by adding loop cuts and dragging them out at the top to form the cylinder, using the mirror modifier to keep it symmetrical. The glass was created by simply selecting the glass BSDF material and changing the colour.
Overall, I am pleased with the end result.
