A poor first-half showing from Preston saw them go in at the break a goal behind. But they twice came back after the restart to snatch what Collins believes was a credible point.
He told the official website: "The gaffer [Alan Irvine] said a few things that we needed to change and we did that. We were told the simple fact we needed to improve.
"I think the improvement was there for everyone to see but obviously they are a good side we were playing against, they pressured us and could have made it 3-1 in the second half. In the end, though, it was a very good result for us.
"This is something we will learn from and it is a good point against a really good side and we have nothing to fear against teams like that."
