Your image is worthy of extra work given its special moment that it captures, of a wedding party with the bride. They will all cherish this image.

To begin, you must accept that more one way exists to skin a cat. So others will present their editing methods.

My editing included the Patch Tool, the Selection Tool, the Spot Healing Brush Tool, and the Clone Stamp Tool (in its Lighten, Darken, and Normal modes).

I got rid of the other pole (because a distraction) using the Spot Healing Brush Tool. This part was the easiest. One only has to set the brush size and then drag it over the object, to erase and blend it in one motion.

Note that I also used the Transform Tool in Adobe Camera Raw to right the image before removing the poles. It rotated slightly clockwise.

Note as well that I named the tools I used but without going into a lot of detail which would take paragraphs. I suggest you go to Adobe online for its tutorials showing how to use its various tools. You will thank yourself.

Now is the time for you to apply yourself to learn the powerful editing tools that Photoshop offers. When using a tool, work on a new layer, so if need be you could simply delete that layer with its changes. Bear in mind that you can reverse edits also with the History tool.

Please see my edited version of your image. It is not perfect but very close, just to illustrate the improvement possible in a short time. I also took the liberty of using the Levels Adjustment tool in Photoshop to adjust the black and white points and to brighten the midtones a little for a better exposure.

RANT: I end with a final note that the skin tones of the ladies appear reddish and orangish. Adjusting skin tones for a natural look involves other adjustments that I skipped here.

In my experience I've found that photographers add so-called warmth to skin tones for a healthy look.

On the contrary, I believe they avoid careful adjustment of skin tones because of the time-consuming difficulty of achieving this outcome.
The pros want to finish their work pronto so they may submit their invoice for pay. In turn, others following them have copied this unnatural look of skin tones.

Good luck in your efforts to learn photo-editing for better results.
