The Scottish defender gave the Tractor Boys a lead in the first half, but Christopher Burke was able to level the scores for the home side after the break.
"We're disappointed to have only taken one point today because, let's face it, we deserved all three," the team's Twitter account quotes the 28-year-old as saying.
"We performed well again but we've got to start killing games off and we had the chances to do that today.
"We've got to look at the positives though and focus on picking up points with two home games after the break."
Ipswich sit 16th in the Championship table.
