Something isn't quite right with this image

[AndyD]

Hi All,
I haven't been here for a while.
I am working on images for the hero image of a website for a security company. I have take 2 of their images, one of the Guard on a building site and the other of a personal alarm.
My intention is to highlight the personal alarm as it is a service that may be offered to the company's clients. So I extracted the personal alarm from another photo, added a yellow border and also fill with transparency. But I really don't feel the image works. Is the background image of the yard just too bright, should it have a semi-transparent gradient overlay? Oh I don't know. Any suggestions would be very welcome please. I will be saving as a WebP for the site but have to do that online I guess. I am using Xara Photo & Graphic Designer 17.1.0.60742 DL x64 Dec 10 2020.
Thanks in advance.
