Raven-game design / run and collect concept art

This is concept art from moment of my Raven-game, when you have to run and collect mails in city .
I used photoshop with this, I am not used to use it so it's not the style as I normally do at home...
But here's my idea and little fun hehe.

Idea time is at super early morning, you have to collect mails before sun shines and run in the city. Also that time at night there's evil monster at the streets so it gives more challenge for player and rivers to jump at boats with.
