here's a download for a .zip file. open the zip, inside you'll see a folder with the same name as the zip file. click and drag that into your Custom folder. https://www.dropbox.com/s/6k6m49scvg89k93/crosshair_sasukeyy_thalashseeker_muzzleflash.zip?dl=0
I did not test it in game but it should be fine.
When playing TF2 use cl_crosshair_file "" in console.
Alternatively go to Options > Multiplayer and set your crosshair to None.
You can also change the colors and size in game. I recommend setting the color to white (then the wings are white and the dot in the middle green)
Also I used an old base file which also contains smaller explosions from rockets/pipes/stickies. It reduces visual clutter and gives slightly more stable fps when there's a lot of spam but if you don't want that let me know.
in case anyone wants to use this as base file for their own crosshairs:

the smaller explosions and more options for them can be found here. Open the relevant .txt files and follow the guide (scroll through the thread)

The Thumbnails folder contains 4 crosshairs but these are all the same file. crosshair1 is generally slot1 weapons,
crosshair2 slot2, crosshair3 slot3 + special weapons, I think crosshair4 is for the ambassador because I hate how it rescales so I use a different crosshair for that usually. You can change all of these in the txt files ofcourse
