Today's starting point: 12:12
Ending point: 13:53
I'll be honest, I was mostly going on vibes today and not bothering to stop the video ten thousand times to figure out exactly what was going on. My version may reflect that. Sure, it's fine.
Our starting point:
Step 1: Import the bridge
Once again, this bridge has been extracted from its background. I'm actually not sure it's a real bridge — it may be a render.
This involved using the layer warping tool that I can't find in GIMP, but I made a cage around it and warped the cage. That seemed to work pretty well, though it does fuzz the edges a bit. I think that's only visible when you're zoomed in, but it's noticeable then.
Step 3: Add highlights and shadows.
I think I got close. In any case, this is what I ended up with. Tomorrow I'll deal with the cliff edge on the left that is passing through part of the bridge.
