Having just read Joseph Conrad's Heart of Darkness, I was motivated to capture a sense of the oppressive heat and untameable wilderness that the book so effectively describes. Here's my effort. The book follows a maddening journey down an unnamed African river on a steam boat full of cannibals and "pilgrims." On different bends of the river, company men would come out of their outposts and watch the boat go by, seemingly trapped in their isolated stations.
The boat is modeled after the real life steamboat that Conrad worked on when he was a professional sailor. The basic shape was rendered in 3D and imported into photoshop, where I combined it with some new foliage painting techniques I'm working on.
This is awesome. For a more oppressive feel, I might go with some slightly warmer color tones, and some haze, like the sunlight is diffusing into thick water vapor (not that I could do anything this awesome though...). What is your foliage technique? It looks great!
Those little details and the realistic structure (and great lighting) of the man-made things are what really brings this image (and really most of your images) forward, very well done there!
I feel the greenery could do with some more "life" though - whereas I understand you might aim for an oppressive feel here, I imagine some subtle in-mixing of some more unexpected hues like purple and turquose into the forest canopy would do a lot to make it even more striking. Just an idea.
