Twilight Solarplate Etching

I thought that an apartment building in the evening would be just the thing to do to add a little color to a solarplate etching. This is the next in my building series. It's a building in the city where my studio is located.  I struggled with the plate exposure at the beginning as it came out overexposed at the top and bottom but once I ordered a new plate and exposed it again, the problem was solved. Another mysterious problem in the world of the printmaker!
