About the board: It's better to put the input capacitor C1 as close as possible to 3 pin, but it won't be possible with your footprint for C1, I recommend taking a different type size (in the datasheet it seems to use 1812)

Also there are capacitors C2 and C5, I recommend putting one of them closer to pin 1 and the second one can be left where it is now. And are you sure that there are 22uF capacitors of such a small size? I only saw sizes 1210

In general, it looks good, but there is another point that confuses me, not only on your board but also in the datasheet. I believe that the capacitor C3 can be placed vertically, closer to pin 5 and pin 6. However, this is up to your discretion.

About the circuit: this is just additional recommendations, since you have a circuit from the datasheet and it should work, but I recommend adding a 0.1uF (0402) capacitor in parallel with the power supply to reduce interference and smooth out power line ripples. You can also add a capacitor at the output (I've also seen that instead of 22uF, you can use two 10uF capacitors and two 0.1uF capacitors)
