I went to Joshua National Park with a couple of my friends.
These gouache sketches were done roughly in 10 - 15 minutes. As usual, comments or crit are always welcomed :)
These two were done in a bit longer time (20 to 30 minutes). The tree sketch was done at a local park in Azusa, and the building sketch was Pasadena City Hall. It became a sketch because I got kicked out by a lady saying that the site was reserved for a wedding which start approximately in 3 hours.
