Sodium (Na) progression

I have been working on my drawings for typography. I thought drawing 30 sketches for my element (Sodium, Na) would be difficult, but it turned out to be somewhat fun.

I think these are my final fonts, but I am not 100% sure. I really like DIN 1451. Sodium seems like a very loose font, and no serifs. Mostly because I think of table salt, and that seems like a loose laid back kind of imagery.
