Personal branding (logo design) - an evolution

Logo design for myself to give my identity a more personal touch.

The logo is made up from only circles and squares, and represents the letters 't' and 'b' on one hand, and a 'drop of ink' (inside the circle and on the top of the logo) on the other hand.

Because I've drawn thing all of my life, I thought it would be funny to transform my personal logo (tB) into a pencil, BIC pen, marker and Apple Pencil.
