New image, 1504x1360 px. Imagine you are standing in a clearing on top of a mountain somewhere. Think about what the hills below you would look like, with the shading from the sunlight (coming from the right, off the image) taken into account as well as the way the rivers carve through the landscape. Now make that in Photoshop using the Pen tool to make the shape, and then the Burn tool to make the shading. Make two layers of it, one behind and above the other. Right click on the pen shape with the pen and click on the Make Selection button to turn it into a selection. Also add a flat plain behind it. Give the flat plain a gradient overlay from yellow on the bottom to light blue on the top, with blend mode Multiply. Now, go to the internet and find an image of a forest from above. Copy and paste it into a new layer. Use the Clone Stamp tool to expand it until it fills up the whole image, similar to the method used in Portfolio 2. Now duplicate the layer, and shrink the duplicated copy a bit using Free Transform (but use Clone Stamp to make it fill up the whole screen again). Move the layer with the smaller trees above the layer with the more distant hills, and the layer with the larger trees above the layer with the closer hills. For both layers, apply a Clipping Mask using Layer>Create Clipping Mask. Set the blend mode of each one to Overlay. Set the foreground color to orange-red and the background color to yellow-brown. On two new layers, do Render>Clouds. Place one clouds above one tree layer, and another clouds above the other tree layer. Set the blend mode of both to Color, and apply a Clipping mask to both. Also set the opacity of both to 80%. On the lower Clouds layer, do Hue/Saturation, changing the hue to +10 and the brightness to +20. Add a background layer behind everything else with a sky-looking gradient. Add a layer above it and make some very light orange lines across the sky with the Brush tool, then use the Smudge tool to turn them into what look like clouds. Add a small Gaussian Blur to the lower Trees layer.
