A great effort - pity the blade engraving suffered but with the amount of rust to come off it was hardly surprising. The only bit I thought might be a 'killer' was that area on the front side at the edge - I have seen so many where the edge just crumbles and takes a good depth of blade with it! Yours seems to have survived that though pitting is evident. If it's not going to be a showpiece I wouldn't worry too much - removing the pitting there totally may well peforate the blade and that's not good! I think you have done very well, first razor or not. Now get an edge on it and attack the stubble!
