I know this is in a bit of a funny order but i found the originals and thought id better upload them here to show progress throughout the project. I wanted to use one point perspective as this method shows a sense of depth and i just like the style and effect. My first background idea was for the gang members to be standing in a darkish alley way to try and portray them as back street characters, characters that are wanted so try to keep out of the lime light.
For the police characters i have produced a high street so that it looks like the armed police are patrolling or looking for something/someone, this is also the same style. I like the two backgrounds as they are fairly detailed (might prove an issue when adding colour) and could easily work as backgrounds holding the characters.
