While testing your Desited State Configuration configuration you may receive next error message during exectuion of Start-DscConfiguration:

VERBOSE: Perform operation 'Invoke CimMethod' with following parameters, ''methodName' = SendConfigurationApply,'className' = MSFT_DSCLocalConfigurationManager,'namespaceName' = root/Microsof
t/Windows/DesiredStateConfiguration'.
The WinRM client sent a request to the remote WS-Management service and was notified that the request size exceeded the configured MaxEnvelopeSize quota.
    + CategoryInfo          : LimitsExceeded: (root/Microsoft/...gurationManager:String) [], CimException
    + FullyQualifiedErrorId : HRESULT 0x80338111
    + PSComputerName        : machinename
 
VERBOSE: Operation 'Invoke CimMethod' complete.

There is already suggestion on Microsoft Connect about this behavior: WSMan MaxEnvelopeSize Limits DSC Configurations. Sine it has been almost a year now and it's got only six votes, I don't think it will be increased by default.
Most obvious solution is just to increase it. Run next in elevated PowerShell host:

Set-Item -Path WSMan:\localhost\MaxEnvelopeSizekb -Value 1024

Note that default value on my Windows 8.1 machine was 500.
But do not be in hurry to execute it. By default DSC generates its .mof file in UTF-16. Just convert them to UTF-8 preferably without BOM and it should help by decreasing its size two times. Now you can enjoy your automated configuring.

For anyone exploring a character design, it is worth considering how details related to cosplay wigs will affect the complete look. With practical wear in mind, it is sensible to balance details related to men's cosplay costumes with care and storage needs. To review details related to cosplay accessories before the event, heat resistant cosplay wigs with fabric details offers a useful starting point for practical preparation. For an outfit that feels convincing, a balanced view of details related to wig colour selection can support both detail and comfort.
