If I may add, adding a little bit more contrast to your characters (or a subtle rim light) could help alot, we understand that it's a dark vibe, but with a tille bit more light on overlay or soft light it would make a huge difference!
I also agree with @kyupol 's comment about speed lines and blurry movement, it can also really help to suggest the direction of your characters
Here's a simple example
Otherwise, you did great, the style is great, you are great!!
