im absolutely blown away. they're so amazing ! but there are a couple things that i feel could be added. while it doesn't look bad the way you're currently doing it i would recommend trying to blend skin tones in with its background so they go together a little more. a great app for that would be something like vsco. one other thing is adding more textures. while it's a small part and not really necessary it makes most graphics look a little more styled. i'd recommend using more light textures to be exact. if you're using a mobile device then i could give you more recommendations on apps. i also have a weheartit account that has multiple sources for your graphics if needed
