Bottle of mana (3D challenge by Kaino University)

Personal work for the contest, Week #9. "Potion" by Kaino 3D Graphics University. I found out about the contest late, two days before the deadline. As a result, there were only two evenings left to work. I start searching for references, find one, and start doing a blokout. Next was the basic modeling of the bubble shape using loft and curves. Modeling, texturing, and rendering were done in Blender. No third-party software was used.
