Sketch progress + vector

Logotype I've been working on recently as part of the upcoming rebrand of the Keep Calm Gallery. In an attempt to make my portfolio updates less daunting, I've tried to be more comprehensive about documenting the drawing process while doing it: top left has some early explorations and the rough draft; below is the tracing of the draft (after fixing it up in Photoshop) using an old laptop screen; top right is going over the outline properly and below that, the final scan.

The vector is approved and I'm finalising it over the next couple of days – any suggestions for things to tweak are more than welcome.

Full size photos and bigger vector attached.
