I would love this in game.

so nice！

This is an absolutely phenomenal skin for an underappreciated pistol. Most of my Five-SeveN skins I use in-game are Valve-made ones, because (aside from the Fairy Tale) I haven't found any of the community made Five-SeveN skins to be worth using. This would easily become my new favorite play skin.
I've got to agree with the first comment here, the textured black grip really brings the whole skin together. I love seeing creators get creative with the weapon itself as opposed to the design for any given skin. As in, I feel like the grip you guys created should have been the default grip for the pistol all along, and I love that. You could have easily gone crazy with the colors and made the fade extend along the entirety of the flame decals, but you restrained yourselves and made only the tip vibrant, and I really like that you've made that design choice. It's such a refreshing design that I don't think I could critique.
You 100% have my vote for this to appear in a future case.

Yo this is looking CLEAN! Glad you kept the black grip, it ties it together so well!
