Thanks for the kind words.
Well I didn't look at the clock

But it didn't take me long. Really easy:
- Background is a rectangle with a gradient on it which fades from orange/red to a dark blue to an almost black blue at the top
- lower half is solid black; I simply drew a line across and around, then duplicated the background and used Path -> Intersection to get a bit that fits the drawing
- The pine trees: I drew the left half, cloned it and flipped the clone horizontally, combined the two parts and removed nodes that didn't fit, then cloned it a bunch of times resizing and changing the shape
- The leafy trees were the most work, I created one, cloned it twice and changed the clones around a little to make it not too similar (I still think you can see that it's the same basic tree).
- The moons are simple again; create two circles, make an intersection for the dark part and a difference for the lighter part; clone and change colors lightly so I get three moons
-> Done.
I am using four layers, in this order, low to top:
- Background
- Stars (so far empty)
- Moons
- Trees
I'll add some stars later today, and see how that comes out.
