Looks OK, considering that you lapped a heatsink and a CPU for the first time.

BUT, I must say that you did a perfect job in rounding all the corners/edges.
Either it's the pics that make it seem like it, or you really did round all the eadges (CPU and heatsink), i.e. you didn't apply even pressure. Next time, please take care about really applying even pressure. You want the surface to be flat, not rounded.
