I'm Hardily one for a Critique, but I'll give it my best, bare with me.
I've come to like your characters more and more. This piece Captures your Urban theme very well in your girls attire and graffiti name drop.
Her the logos in the hat and hoody does seem to come off alil dull in detail as they seem flat to the image rather then adjusted to the clothing.
I would say the mix match detailing over all is a distraction, but it seems add to the charm of your work overall.
The poster background was a good decision of direction.
This would actually makes for a very good poster or flier in onto its self. hinthintsellsell
