Well the skin will be tight for a while due to the swelling in your hand. Even if it does go down it will hold some of the swelling due to the amount of damage you did to it. That may take a few weeks before it goes completely down and then things will ease up some. Having feeling at this point is really a good sign. That shows promise. Full recovery is always relative to the amount of total damage that is done. Still from the looks of your photos I believe that you will end up with only a small amount of loss. Stay tough and just know that no matter what happens that you are still going to move forward. Positive thinking can create miracles so to speak.
I have to say that I have seen much worse. Do you watch the "Home Extreme Makover" show? The British guy tore his hand up with a cutting tool with a chainsaw disc attached to it. It mangled his hand so badly that he never thought he would regain the use of it again, but he is nearly back to full use and still doing the show as a master carpenter. No worries mate.
