Countryside


Sky

New canvas - 800x600.

Set the Colors to 2 colors (similar shades of blue or another color if want to do night or a sunset sky). 

Select the Gradient Tool. Drag it up/down the canvas...


Your layer looks like this...

Mountains

Insert a new layer...then rename it "mountains".


Select the Brush tool, set it to a bigger size (around 20 ), and increase Hardness to 100%...

Set the Colors to the default...then set the Primary Color to a brown/green. You may need to click on "More" and then play with the color settings to get a color you like...


Now draw the outline for your mountains, something like this (make sure you draw it off the sides...

Select the Paint  Bucket tool and click in the mountain area a few times to fill it in like this...


Your layers should look something like this...

Sun

Insert a new layer, call it "sun".

First select the Shapes tool... then choose the Ellipse shape and set it to draw fill only...

Set the primary color to a yellow...

Draw a yellow-filled circle  near the middle of your canvas ...

Then move the layer down below the mountains layer.

Select the Move tool...

Click on the canvas and then drag the sun to move it to where you want it behind/between mountain peaks...

Then get rid of the dotted outline (CTRL+D).

Go to Effects>Blur... choose "Gaussian Blur"...

Then play with the slider until you get the amount you want... and say OK.

So you have something like this now...

Clouds

Insert a new layer, call it "cloud".

Make sure your foreground color is white; use the switch arrows...

Draw a cloud shape with the Brush tool (make sure it's in the middle of the canvas, not touching/off the edge of the canvas)

Then go to Effects>Blur... and set to "Fragment"...

You can leave it with the default settings to get something like this (or play with the sliders/amounts a bit)...

Duplicate the cloud layer twice...


Move each cloud to where you want:

  1. Select the cloud layer you want to move.
  2. Click on the canvas with the Move tool and drag the cloud to where you want it.
  3. CTRL+D to deselect the outline.

Repeat these steps for each cloud.


Grass

Insert a new layer, call it "grass".

Use a green Brush and paint the top/outline for your grass near the front of the canvas, try to make it like grass, not totally flat/straight. Make sure you go off the sides...

Then use the Paint Bucket and click below the outline a few times to fill it in completely...

You'll see it in your layer...

Mountain Color

Before you start drawing the tree, if your mountains are brown/green, you may want to change the color of them (if you want to draw a tree with brown and green) - select the "mountains" layer and go to Adjustments>Hue/Saturation... and drag the Hue slider to whatever color you like...

Trees

First tree

Insert a new layer - call it "tree trunk"...

Draw the tree trunk - make sure you're not drawing off the edge...

Then insert a new layer for the "tree leaves"...

Draw the background leaves color with a huge Brush (size 100) and create a shape like this...

More trees

You can draw different trees - just make sure you draw the trunks and leaves in new/separate layers. Or you can save time and just duplicate the tree trunk and leaves layers - change the colors (Adjustments> Hue/Saturation) and move them over...
