This project helped to improved my UV skills. Making sure the planar map was square instead of rectangle and rotating it properly helped me get a much better UV layout. Another tool that was extremely helpful was Create UVs Based On Camera. When I forgot to create a new map, I could get the UVs from the camera angle without having to recreate my work.
For the box, I combined projections with layered textures to create a new look. In this case, I added dirt along the top corner and side of the box as well as the fire dragon sticker.
The glass was done with more layered textures and projections as well as reflections and refractions. The liquid in the bottle was created with caustics (those purple shadows).
