Nice work, but I have a few suggestions.
This hat has its neck-strap added on very oddly. The strings appear to be on the hat’s brim instead of under the hat. I’d consider making the black-brim outline go all the way around the hat and hiding the string.
The hat is very close to the top of the logo, and it would be much better if there was more spacing. Consider moving the word “Murder” and other items associated downwards.
The following corner-triangles are not needed. While the entire logo is dark the corners are bright white and it doesn’t make much sense.
The logo is off-center! The cowboy hat should align with the center of the image. The radiant background is just to the right of the logo.
That’s about it. Hope I helped.
