I'm not into that type of mood, but checked from my interest in terms of production ideas and I think it is really nice work. The hi-hat pattern fits perfect and makes the beat really dynamic, I liked the reversed synth/sample which is the main theme to the track. Mixingwise the track seems to be well-balanced. I would think about making a short section/transition that would stand out more from the rest of the track, basically I think that the track would surely benefit from more variation.
If you'd like to check my tracks and let me know what do you think, please reach out my signature, any feedback would be much appreciated.
