At the end of the Layer Mask part, I've added some additional information. This does not change the image, but it's good to look into.

Some more information about the layer mask is below, which can come in very handy if you want to make specific adjustments to the mask. It's not needed right now, but we (or you) may want or need this later. If you want, you can experiment a bit. SAVE the image, experiment, and then load your previous file again if you wish to do this.
- You can paint on the layer, by selecting the Layer rectangle.
- You can paint on the mask, by selecting the Mask rectangle.
- The Layer rectangle is the left one, the Mask rectangle is the right one.
- The one you select will be outlined in white.
- You can paint ONLY black/white/grey on the mask. if you paint with another color, GIMP will convert this color into its equivalent greyscale value.
- If you wish to see the mask instead of the layer itself while you are painting or adjusting the mask, then press and hold ALT and left-click on the mask. The mask will appear in your image, and will be outlined in green in the layer palette. NOTE: It is possible to make the mask appear, and still have the normal layer active. Left-click the mask to make sure it is active for painting.
- If you want to turn the display of the mask off, ALT-left-click on it again. The same applies: you can turn the display off, while keeping the mask active. To make sure your layer is active, click on the Layer rectangle.
