Here is kind of the start and basic layout i'm going to use. Going for a single sided board.

Maybe take C1 and flip it so it is outside the footprint of the module. You can then take your 2 traces and route them under the module instead of wrapping around. This will allow you to have a solid ground pour I think. You can do the same for C2.

You might also think about adding a pull-up resistor for the enable pin rather than directly connecting it to Vcc. This would allow you to externally disable the module if you ever wanted. This has a very similar, if not identical, function as reset and the module you are using doesn't expose the reset pin.
