Not sure who the artist is but I really admire the use of tape to put up art, it subverts the power frame and such like, brings the art back down, negating a sense pretention that can sometimes accompany an art work. Also The use of 'barbie' pink to hide aspects is similar to what i have been doing recently. Although would it be more powerful with just one image, does things hide whilst in a grid form?
This is probably one of my personal favourites for watercolour paintings. This drawing just allows the viewer to see the great difference in contrast and tone from the light source. As you can see, the light source piercing through the windows are yellow/orange-ish whilst fading gradually to blue and dark grey. I love it!
