Enabling Sharepoint Features With Powershell - sharepoint

Question

I am new to PowerShell and have been asked to modify a script that is used to activate features on a site. The script has some latency issues between the two feature activations, so I decided to make a new function that will enable the feature and sleep or delay until the feature is finished enabling. Will this work? And if so, how can I tell that the feature is finished activating?
# This is a function that enable's a Sharepoint Feature and Sleeps Until Its Finished Enabling
function Feature-Enable
{param ([string]$ID, [string]$URL)
#Enable Feature
Enable-SPFeature -Identity $ID -url $URL -Confirm:$false
#Sleep Until Feature is Done Enabling
}
#Set parameters/variables for script
$serverName = "someServerName"
$rootwebUrl = "someRootUrl"
$currentpath=Split-Path -Path $MyInvocation.MyCommand.Path -Parent
$siteURL = "http://" + $servername + $rootwebURL
$start = Get-Date -DisplayHint Time
# check to ensure Microsoft.SharePoint.PowerShell is loaded
$snapin = Get-PSSnapin | Where-Object {$_.Name -eq 'Microsoft.SharePoint.Powershell'}
if ($snapin -eq $null) {
Write-Host "Loading SharePoint Powershell Snapin"
Add-PSSnapin "Microsoft.SharePoint.Powershell"
}
# Active Site Collection Features (in order)
write-host ""
write-host "----------------------------------------"
write-host "Begin activation of site collection features"
write-host "----------------------------------------"
write-host ""
Feature-Enable –identity "3cbf5d1e-ff2e-48d2-82a4-99b060381268" -URL $siteUrl
#NOTE: POTENTIAL LATENCY ISSUES. MAY NEED TO INSERT DELAY TIMER!
Feature-Enable –identity "bbde524e-9293-468e-84f7-fdb763ffa309" -URL $siteUrl
write-host ""
write-host "----------------------------------------"
write-host "Activation of site collection features - DONE!"
write-host "----------------------------------------"
write-host ""
$end= Get-Date -DisplayHint Time
Write-Host "Started at: " $start " Ended at: " $end;

function WaitForJobToFinish([string]$SolutionFileName)
{
$JobName = "*solution-deployment*$SolutionFileName*"
$job = Get-SPTimerJob | ?{ $_.Name -like $JobName }
if ($job -eq $null)
{
Write-Host 'Timer job not found'
}
else
{
$JobFullName = $job.Name
Write-Host -NoNewLine "Waiting to finish job $JobFullName"
while ((Get-SPTimerJob $JobFullName) -ne $null)
{
Write-Host -NoNewLine .
Start-Sleep -Seconds 2
}
Write-Host "Finished waiting for job.."
}
}
