It looks good, especially for a first try at it. If you have seen my videos on mono work, I'm a fan of scratching and erasers and utilizing the natural white of the surface to stay way from the blue shift. I started mine with an over reduced grey and added a little black to my grey as I build my shadows up to its darkest points.
Andre I have the opaques and on the paper it absorbs a lot so it looks like it's "bleeding" back into the white when I paint over the black. Will order a set of transparents as well or maybe try the Dala Inks heavily reduced.
But yes thinking of getting an electric eraser and to begin scraping as well.
