Oh, this is an interesting scene, lol! I love the overall colors and vector work.
I would only suggest not to blur things so much in the future; some things look way too overblurred, like the guy's clothes and hair. They're blurred so much that the shading barely follows the lineart. Blur tool shouldn't be used to make things look 'soft'; blur is used for depth and perspective mostly. If you want to achieve that 'soft' look, try using gradients and/or vexeling. You can even use the smudge tool to better blend colors.
Keep it up!
