Love the color
So here I'll first discuss the color you actually have great use of color here and make it work well these two colors work off of each other's other like light and dark do. You can actually brighten up the yellow areas and make them shine off very well with the red would create a great light effect off the yellow and onto the red. On another improvement option you may even want to think about adding some yellow to the background. Maybe just some pins or postits in the corners like it's a poster of some sort but anyways those are just a few ideas that may help and improve on a nice piece here great design though it's very cool indeed
~~THINGS TO IMPROVE ON~~
Some brighter points and some extra yellows
