Expanding my skills by adding in a self-drawn tree (I wanted to use a picture I took of a cool looking tree nearby, but the resolution just wasn't high enough) and using some filtering effects in the clouds natively in Inkscape! Also added a tower from a picture of a mountain nearby.
This is also an experiment with a bit of sci-fi feel with the two moons, though I also experimented with a strange dotted background. In the end I kept it simple with just the fixed purple and pink stars. I really like how striking this came out!

It took a lot of fiddling with color processing to get the effect I wanted from that daytime picture!
As always, images from newest to oldest.
Update March 5th 2018 - on further inspection, lowered the darkest purple layer to a near black.
