Minimal Arduino on a (small) stripboard

This is the schematics of a minimal version of an Arduino on a (very small 10x16) stripboard. It uses the main components from the official Arduino schematics to replicate a project on a separate board (does not include power supply circuitry and USB serial communication).

Note: with respect to the previous posts in this blog on other minimal versions, this one uses a more correct wiring of the analog section (as in the official board, and according to ATMEGA328 datasheet).

UPDATED: here's a picture of a physical realization:
