Hey good job! Be sure to adjust the FD outer-cage parallel to the chain when you're in the tallest gear, big-chainring/smallest-cog. If you have a newer FD with a wedged-shaped cage (narrow in front, wider in rear), this allows the chain to sweep a wedge-shaped path (looking down from top) as you go through the cogs in back. The FD cage will sit outside of this space and not rub throughout the entire sweep-range.
On older FD with parallel cages, I insert a longer bolt with a 1/8" spacer at the rear where the two cage-halves bolt together. This gives it the wedge-shape to prevent rubbing across the entire range.
