Looks to me like you have done a mighty fine job without anyones help.

The shot just needs converting to monochrome ( black & white to you and me). I have done this with the channel mixer.  Settings here Red = 100 Green = 0 Blue =0  Constant = 0 and tick the monochrome box.

IR is a matter of finding the right settings and the right scene. I think this shot has probably over exposed just a little bit (too long exposure). I can't be sure of that though because this is only a small image and making it this small could be the culprit. I would go with something a little less exposure next time, but I don't know how you arrived at the setting so I can't tell you exactly how to do that. The advantage of having it slightly less exposed is that it will leave you more room for manoeuvre in making adjustments in postwork. Common adjustments might be adding a diffuse glow or noise and adjusting levels, contrast, etc.

The only other thing to add is and I am sure I speak for all of us here: any help, advice , tips  etc.  given in this forum is given freely because we want to help. Nothing pleases me more than seeing someone use something I have said and get some success with it.  So please, I don't believe in secrets it is better to share knowledge, it is to the benefit of everyone including the person giving. You are free to use it and post your images in the gallery - if you don't I will always wonder if I wasted my time and anyone ever read it.

 

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
