Beautiful rich, vibrant blue on those spiders - love it! They're Reaper, right? I have a few waiting for paint (this "waiting" period can end up being a few years long...), and this is some nice inspiration.
The Congo scene is also wonderful - excellent basing, and I love the muddy trouser cuffs on the Colonial types.
A really good matchup - very different miniatures, completely different "eras" (fantasy v. historical), and even the lighting of the photographs is different (bright "sunny" lighting for the Congo, and darker shadows for spiders), BUT, despite the differences, this is a very tough call. Fantastic!
