[Help] How to edit the Player Destruction HUD

So I've been following Egan's Player Destruction Guide and I'm having trouble following some things.

So far I've made a copy of the HudObjectivePlayerDestruction.res file into tf\custom\CriminalBunny\resource\ui and added that code to the start, as the guide says.

Where I get a bit lost is in how do I change/add custom icons, like the UFO and the Bottle Icons.
I saw that Watergate have them located in the ../hud folder, but where is it? Where should I put the custom icons then? I tried to reverse engineer things a bit and this is how far I've got. I got lost.

Am I doing things the right or wrong way? Am I missing something? Any type of help is welcome
Thanks in advance

Bump because this didn't get enough attention even I forgot about it
