#1 Composition:
If you have writing in the image it is important to have it readable as you have done here especially as the Monument is your main subject.
Look at the line along the bottom of the monument and the bottom line of the frame. Make them level. The foreground is not cluttered and you have the subject out of the center. Now look at the background. The Capitol Building, especially the dome is crowded in close to the monument, even appearing under the upper lip of the stone. The building needs space to reach up into the sky, moving slightly to your left would have done this . The flag pole too is just a white stick, you chopped off the top. Leaving space between major subjects in the foreground with major ones in the rear adds depth. Moving over, too, would get that flagpole from blocking out some of the building. Monument, state flag and State House might be a nice relationship, but the pole as is does not help anything.
You were not able to fit in all of the building which is fine, but maybe a slightly tighter zoom showing even less, but bringing the center and dome closer much show it off a little more.
Exposure: The building is washed out by the strong sun where as the monument is in the shade, look how much sharper it is. The sun washes out contrast, so detail is lost on the building. This would be a good place to try an HDR merge. Over expose the sky then bracket down to a 2 stop under exposure darkening the foreground and then merge the results.
