A more detailed analysis can be found here: https://gamesartist.co.uk/honey-potion/ , however broadly and in general, this project was created in ~1 - 2 weeks with a focus on shader development. While attempting to mimic the 2D design produced by Anh Dang, which can be viewed here https://www.artstation.com/artwork/d8a2v1 

The primary advancements of this project come from the glass and honey shaders in conjunction with the lighting, whereas the modelling and hand painted textures are fairly self explanatory. Which employed a projection method to both accurately and efficiently develop the model, textures, and visual development. The honey shader is a soft gradient falloff shader, which produces an edge glow similar to a Fresnel node. While the glass's 2D properties are the product of a highly contrasted falloff shader producing edged lines weighted effectively by the objects curvature or tangent view space.
