Not bad for first time picks, I would suggest however that you smooth them out a bit more in order to prevent damage to the pins and keyway. The sharper the edge on your pick, the more likely the chance of damage in the long run.
Also I agree with Trip Doctor, you should take off the metal a bit more such as in Pick #3, This will prevent the accidental setting of the front pins while you pick the back ones.
And as always, don't pick your own house locks, unless you also plan on learning how to fix them!
