I cut the man out of the background and coloured pieces with a few filters and patterns.
I cut out the helmet from another source and resized and warped it so it fit on the helmet of the man. And coloured it a bit.
I choosed a background photo from my own and resized the rhino and man so it fit nice in the image.
I used the healing brush tool to erase the parts of the photo, that didn't fit in the picture and used the burntool to add some shadow for the rhino.
step 4 of 4
I used a gradientfilter for the background to give it all a outerspace atmosphere. And added all together.
