How can I check if my pronunciation is actually 'native' enough?

I’ve been recording myself reading Irish poetry to really nail the nuances, but I have no way of knowing if I’m just practicing my mistakes. I’m preparing for my first real conversation with a native speaker next month and I’m terrified I’ll be unintelligible. I’ve been considering using Chickytutor.com to analyze my recordings for subtle pronunciation slips—has anyone used this for Irish specifically to get feedback on their accent?
