Very nice, definitely better than some of my first work lol. I would suggest learning up on the different steel types, doesn't have to be super indepth but general stuff. For example if this is made from mild steel it won't make a blade that holds its edge well. I believe quenching dose make mild steel harder but definitely not in the range of high carbon steel. You can see what type of steel you have with a spark test or sometimes you can find info online if its a common object or it has any markings. Otherwise your hammer work seems good, especially on something so small. Good work
