That looks really nice well laid out and well painted.
The new scenery sets are apparently very good value if you can make use of them
, my brother has bought a couple of one of the sets because he has some ideas for how to use them, and worked out that it was a big saving on buying the parts.
My brother was debating buying one of the Forge World "realm of battle" tiles* whilst we were over at GWHQ, he was torn between the crashed Thunderhawk and one that looked like it would make a good setting for a landing pad/knight repair bay, in the end he didn't, but one of our friends bought another 8 of the (new?) Zone Mortalis tiles to go with the 16 he bought a few years back (he's got a garage full of scenery and models from the last 25 years).
I'll try and get the pictures I took uploaded tonight or tomorrow as I always find having a look at GW's scenery gives me ideas, especially the set pieces they do to show off new models, and they had some cracking necromunda stuff.
Also apparently car laquer is great for making something look like it's wet, and thinned down paints applied to upright tanks etc then sprayed with a mister/sprtzer bottle allowing the paint to flow with gravity and dabbing up the excess to get the look of something that has leaked.
*He's got both the standard sets (the city one looks awesome when painted).
