Another sketch from Lisbon

Lisbon, Cathedral (Se), originally uploaded by mc_bds.

Now that the winter rains are here, I like how this sketch takes me back to the beautiful sunny weather this past September in Portugal.
This is the cathedral in Lisbon, sketched and coloured very quickly around sunset (I think my watch was still on Madrid time as noted on the sketch).
I like how I managed to catch a bit of the setting sun's luminosity in the stone. Light effects are the hardest element to catch for me.
Nothing like a sketch to re-live a moment.
