Richard,Hi Gerry, 10 for effort.
To avoid the silicon from sticking try cling wrapping the surface. The weight of the silicon will press the cling wrap into the little corners. When hardened you can snip or tear away the cling wrap...it's clear so can be part of the water as well. You can re-attach the sculpt with fresh silicon using an old small brush that you want discarded later.
You can work in stages and join with silicon. If I can recall it stays in shape and seldom shrink. I know commercial tube silicon starts skinning the moment it leaves the vessel but if you work quickly and extrude the stuff into a working cup you could add a little food coloring and mix like hell and work from there with a spatula, ice-cream sticks and old soft paint brush.
I would suggest airbrushing the whites in and final highlights dry brushing with a paint brush.
That's my 2 cents...basically 8 sen in Malaysian ringgit.
Cheers,
Richard
I've found out that silicon doesn't stick to sellotape very well, (when I used the 'merge' pebble 'mold' to try and get the final 'fall' into the larger pool) might just give the area a cling film 'coat' - did think of lining with sellotape (but thought about removing it and decided not to!), to see how hard it's going to be to try and get the falls in place and work on them.
The clear silicon I've got doesn't shrink and 'skins' in about half an hour (but remains wet in the middle for about a day) ends up being like a soft rubber which retains its shape.
Funnily enough, I was just getting to the conclusion that I might just be able to use an old toothbrush to try for the splashes (got a couple in the box).
At the moment, I'm grateful for any and all suggestions for it.
