You should be fine - maybe add a 10uF cap after the 3.3V regulator (mind that cap is rated around 10V or better). You don't need two 0.1uF capacitors between the regulators - one should do well, but keep the 47uF.
Be sure not to exceed the current ratings of the regulators with your loads (keep in mind the current for the 3.3V load also flows through the 5V regulator and adds to that load).
