I am trying to configure Qos on our MPLS for citrix. We already have qos running for Voice and it seems to work well. No voice issues reported. Each branch has a full T1 out to the cloud. The vendor Verizon has a GOLD CAR of 512k setup for Voice which we route our Voice traffic over. I would like to tag my citrix traffic as COS=3 mission critical. I have attached out current QOS configuration. Is this ok to do the tagging this way is there a better? Also I have started to add the Citrix tag in there. any help on completing would be greatly appreciated.

You might want to double check exactly what you are getting from Verizon. My experience with their MPLS service, you need to buy real-time bandwidth separately, and other traffic falls into a 5 class model which allocates fixed bandwidth reservations, two drop points on some classes, and uses DSCP markings, not CoS markings.
Also, on non-real-time classes, exceeding the purchased CAR often isn't an issue.
PS:
BTW, your limiting your overall data rate to 512 Kbps.

Not really what you want, I think.
Perhaps something similar to:
(NB: syntax might be incorrect or not supported on your IOS version. You also need to check markings supported by MPLS provider.)
class-map match-any VoIP-Cntrl
match ip dscp af31
match ip dscp cs3
class-map match-all VoIP-RTP
match ip dscp ef
class-map match-all Citrix
!NB: you might want to subclassify Citrix to avoid giving preference to disk-to-disk or printing traffic
match protocol citrix
policy-map sub_int
class VoIP-Cntrl
priority percent 33
!NB: reason for policer, LLQ policer doesn't engage unless there's interface congestion provider, though, likely polices rate
police percent 33
set ip dscp EF
class VoIP-RTP
bandwidth percent 5
set ip dscp cs2
class-map Citrix
bandwidth percent 10
set ip dscp cs3
class class-default
!NB: deactivate FQ to maintain explict other class's bandwidth regardless of number of class-default flows
bandwidth percent 10
set ip dscp BE
interface Serial#/#/# point-to-point
