Basic illustration and game design(ASAP)

Hi there, we need some basic illustration and design. We need a background illustration and a main character. And some design, i attach a pdf to show an example. We need the final work in psd, the background should be of 1024x512px in loop, separate all the elements in layers. The alien 64x64px The wooden boxes should be 64x64, 320x64, 128x64, 128x128 The rock blocks should be 64x64, 128x64 The boxes showed in the image number 4 should be 64x64 and 128x128 px All the items are showed in the pdf file. The main idea is use the example to do some similar, you are free to design a new alien, another background and boxes. Thanks!
