Art for a top down 2D dual stick shooter game

I am working on a top down 2D dual stick shooter. See the following video: [login to view URL] I have the following art requirements, but as always am willing to listen to the winning freelancer's suggestions on the details: Requirements Summary • png format. • Transparent background. • 2D. • Top down view from directly above. • Sprites to be north facing (no rotation required). • Frames must be in a single row, not column. • Each frame must occupy the exact same amount of pixels and have equal spacing. • Walking sprite sheets must cover a full walk cycle with enough frames to keep it looking smooth and natural when looped. The same goes for the death sequence. • At least 128x128(unless otherwise stated) pixels per frame (should be scalable down to 32x32 without losing too much detail). Menu Background Image • Exactly 1920x1080 • Open to suggestions on this one, but thinking concept art type (pencil sketch) type image(s) of something game related i.e. a spider. • example: http://img146.imageshack.us/i/20080220smpf8.jpg/#q=concept%20art BoxArt • Exactly 584x700 • A few dead spiders strewn around the place. • Our hero with one foot resting on a spider. • Gun firing. • Wild look in the hero's eyes. • Full colour. • Game title. Thumbnail • Min 128x128 • Needs to be scalable down to 64x64 and still look good. • Open to suggestions on this one. Bullet • 128x128. • Single image to replace the blue bullet in the game. Spider Lair/Nest • Min 256x256 • I would like to place a few spider lairs/nests around the level for the spiders to emerge from. • I am not concerned about the art of them emerging, as I will just draw them under the nest or lair, so it looks like they are exiting from it. • Maybe make it animated so that it shudders or moves very slightly. • example: [login to view URL]
