EY! I found a reaper concept similar to what you said! It’s by the same artist as the tracer one (effektdmentality). there are a few others they made so i’ll just link them below!

• Archangel Gabriel Reyes
• Renegade 76
• Crosshairs Widowmaker, plus a 3D render of that concept by Gus Mashensic

on another note, if you wanted more of that white and red, you could kinda merge the Archangel concept with this Assassins Creed concept by 3OK
