I went to the presentation of the USK Liège book last thursday.
Some of the sketchers that feature in the book were also there: Florian, Gèrard, Lapin, Antoine and Fabien.
So we took the opportunity to go out and sketch. On friday Gèrard had the bright idea to go to a rooftop of an apartment building overlooking the Meuse/Maas. Mind you: the temperature was barely above freezing point, and there was a chilly wind. Only if you stood in the shade of one of the chimneys, the feeble sun would warm you up a little.
The sketch is the view over the city centre.
By the way: I was on the (French speaking) Belgian television again.
