Heres two sets: You said you wanted some overgrown jungle/sci-fi stuff, which is entirely what Crysis 3 is so heres the concept art for that game. http://www.neoseeker.com/crysis-3/concept_art/ Also Star Wars The Old Republic has some nice art used in a lot of the loading screens. http://www.swtor.com/info/media/concepts Enjoy the art and happy birthday!
Checked through the list and heres a couple soundtracks that I haven't seen listed yet. I ordered them from the ones I like the most to the ones I like the least for you. Terraria- I have 400 hours in this game and some of the boss battle music still gets me hyped every time I hear it. Crysis 2 and Crysis 3- I put these too together, both have some good sci-fi music in them. Strike Suit Zero- Again more sci-fi music though this soundtrack is more relaxed. https://www.youtube.com/watch?v=-TQa2AYadrg Star Wars Republic Commando- This one I'm not sure if you'll like but I still put it in. Its a mix of star wars music and some deep choir singing. Enjoy the music and Happy Birthday!
