This is will show you how to make different sky's like rainy or sunny.
I will show you how to make a sunny sky.
Start with setting the background colour to light orange
Set the line tool.(6 points) And transperancy to around 30.
Start making horizontal lines.
From left up to right down or other way.(like in the picture)
The lines dont have to be 100% straight.
Make lines one over another
Set some more lines. Like in the picture.
Now gho to a darker colour. And make them under the brighter ones like in the picute
Add another darker orange under it.( picture ^^)
Now go to colour yellow. And fill up the holes that are left over.
Now comes the air brush ^^ Go to air brush and keep it at 6 poits but set transperancy to around 40.
And brush over the lines with the same colour as the line itself.
It allready looks like clouds.
Now the white airbrush. Set it to white and the transperancy to around 15.
Use the same technique as on the lines and use the brush above the darker lines.
Now u can add mountains,birds or something beneath it.
Check my drawings they have same technique
