I'm thinking that in addition to my design weeklies that I should also be doing dailies (maybe in three.js if I have the time). The idea will be that the weeklies will be a little higher quality and that the dailies can be complete crap. That way I can experiment with everything and not feel restricted.
This week was a bit short so I just practiced some gradients, shadows, and highlights with this bottle. There's so much more that I could of done, but that's not what these weeklies are supposed to be for.
