Today I managed to make a start on the next video tutorial On creating a waterfall. It's going to be a big project but even with the very basic landform taking shape I can already envision a very cool looking scene.
The hardest part for me I think will be getting just the right riverbed color and the transition from the deeper sections at the base of the waterfall to the more shallow sections just down stream of the falls.
The image above is what I'm using as a reference for my waterfall, I like how there is a small alcove shape that fans out as the river flows further down stream.
And the image below shows the very first stage of creating the basic land form for the diorama.
From what I can see in the reference photo is there is a lot of greenery which is expected near a large body of water however I will also need lots of rocks to form the cliff sections of the waterfall. You can never make too many plaster rocks! I don't anticipate using them all but have more than you need is much better than not having enough.
Oh and by the way... this is just the first batch of molds! I plan on doing this about 3 or 4 times.
