Hey redfinger... use the gnome theme manager to make your gnome taskbar and icons look a little nicer...
Click: Bianca mintMenu > Control Center > Desktop > Theme
Play around with the different themes and icon sets and find one you like. This may mess up your Beryl theme but going back into Emerald after you are done and reselecting your Beryl theme should have everything looking nice.
Best of luck with Linux Mint + Beryl!
