This is from the same western warehouse wall in Colorado Springs, Colorado, as the first five Street Art posts - in the Depot Art District.
This is probably a self-portrait of the artist, but it also may be a tribute to a local hero or a memorial to a fallen friend. In any case, it is a stunning demonstration of this painter's artistry. This "bust" is probably at least 12 feet high. The light-and-shadow technique used to create the features of the image are truly excellent.
This time around, for reference, I include a picture of most of the entire wall:
