Thanks, I tested out all your suggestions, trying various values for parameters.
Finally, I ended up with something that I am not sure if I can get better results with such source image.
Converting to vector with Inkspace was an idea that took my attention most.
The problem was that image lost too much details after it.
So, I started to play with original image to check how some changes may affect results of this conversion.
I used Irfan View and my lastest modification experimental combo was gamma 2.0, contrast -64, and whats most important I guess, using a lof of sharpen effect to highlight details.
Using of each effect and values may depend on image and personal preferences of course, but what I mean is modify image before conversion, especially searching for something that may improve details like sharpen.
In Inkscape, I used "Trace Bitmap" from right click menu and choose default "Brightness cutoff" with 0,45, which was best setting for me in case of this image.
I ended up with in my opinion improved details (noticeable on helmet) when compared to all other methods I tried.
I hope this might be some suggestion to try by someone in the future.
If something else come to your mind, let me know.
Mentioned results below.
