Your pictures are much too tiny. Need to set the camera to 3 or 4 times larger. Then, instead of taking pictures from multiple locations, pick one central location -- in line with front door or center of house -- and take a series of pictures that pan from far left to far right. Stand at the curb and pan far enough that it shows in the first and last picture. Don't substitute a computer generated panorama as it will be too small.

Tried to triple size of pixels but photos won't upload. Going to try doubling size, in hopes it will work.

One would hope that larger pictures would be clearer, but that's not the case. With the fuzziness, bad lighting -- and the camera is changing locations between pictures -- it's plain hard to see and impossible to reassemble. You'll need to use a better camera and be more careful with the picture taking.

On thing that is clear, however, is that the big tree in front of the house has branches hanging much too low and blocking too much the view of the house. You could safely remove any limbs that hang below the halfway mark of the upstairs windows. If you could get that done, it would likely improve your chances of producing better pictures.

What is justifying the need specifically for "columnars"? Usually, one has the location first and identifies the form that works with the location. Here's you're specifying the form and hunting for the location, which is backwards.

It took two days to upload these lousy photos. Had to fiddle around with resizing pixels, etc. Even called Houzz "customer service" for advice - useless. Photos appear large on my desktop computer. I only have a tracfone, which, obviously, is also useless. I will limb up the tree and try getting better photos

Yesterday, every new thread with pictures had very small pictures. It made me wonder if Houzz made a change, limiting their size. Do not know yet. Up to now, the main issue with loading pictures is to WAIT until they become full color before submitting them. If you have a slow connection, it could take a couple of minutes. (But it would be better to remove some low limbs before taking the pictures.)

I'm back and hoping you'll show mercy. Did what I could - only have minuscule handsaw.

May have to upload photos one at a time.

Your landscape should compliment your house by leading the eye towards focal points (usually the front entrance). Try experimenting with different shapes of trees and shrubs (pyramid, circle, square, weeping) on trace paper over the image. Try out different combinations until you find the one that appeals to you most. Now that you have the shape of the plants you want it will be easier for you to select a plant that resembles that shape. Make sure you select plants that are suitable for your climate and micro-climate.
