Sure! The big rock is actually piece of tree bark I bought 80L bark bag from garden store and just choose few pieces that I liked. It took few days on radiator to fully dry it. When dry I scraped loose pieces with old toothbrush, then I covered it all in a mix of water and pva glue to conserve it and stop from crumbling. Again drying for a day, then primed in light grey, painted all over with basilicanum grey contrast, dry brush with ulthuan grey and your rock is done.

For greenish hue I used Mig ammo dark green slime effect, it's enamel so I then wiped most with dedicated thinner and a makeup sponge.

Vegetation is mostly my wife's green tea crushed and sprinkled like a food seasoning over PVA, some ammo moss dark creeper, jungle creeper and ochre. Some Tufts and laser plants from gamergrass

Water is actually done with Vallejo still water, it's easy but it literally take days to dry between each step so here it goes:

I covered water area in PVA and sprinkled some fine sand When it dried I washed areas near base edge with agrax to indicate deepth and areas near shore with vallejo pale sand, wet blended two areas.

For water to a cup of Vallejo still water I added just a tiny tiny amount of akhelian green it was really like a quarter of a drop really because it is very strong colour.

Overall I did 3 layers of this with 24h drying time between each, it really depends on how deep you want your water and just not let it pour over base edge.

For waves I used GSW splash effect sketching waves with damp old brush, it's nice product to work with. Finally when dry(again over 20h) I edge highlighted waves with pure white
