Not bad, good use of the POC Hawk chest/fucking collar.
I think too much red, if you're going "modern day" I might tone down his colors a little.
Also that holster is HUGE! And maybe look into a newer helmet? Those 25th tin caps are looking so dated these days. Not sure what would work best..maybe take the RoC Flash helmet and mod it so it uses the visor instead of the full face mask? Not sure.
I think good start! You have the idea and most of the parts, now polish
