MOD Help please....re: changing my avatar isn't working

Good day MODS.

I've revisited trying to change my Avatar for the last couple years with no luck.
Don't know where I going adrift here but I need your assistance.

I get this far and that's it?

I have not clue what I'm doing wrong.

I want to change the current one to this one.
Can any of you please do this avatar update for me?

Many thanks for your help....beer & pizza is on me!
