Matt Skelton says he is considering changing his style for July's Commonwealth heavyweight title rematch with Danny Williams in Cardiff.
Skelton switched to boxing from kickboxing in 2002
Skelton lost a split decision against Williams in February after a brutal 12 rounds which saw him employ some typically uncompromising tactics.
But after watching the fight again, the 39-year-old admits his "rough and ready style" may have been costly.
"I'd like to be a bit more technical, a bit more pure," said the Bedford boxer.
"Obviously the decision went against me but I've watched it through and I think there are little factors why the purists didn't see it going my way and I'm going to try to make amends."
Sometimes I just like to come and have a fight
Skelton, who only took up the sport in 2002 following a stint kickboxing in Japan, tried to out-bully Williams in London and was warned for using his head in the opening seconds.
And although the judges scored the fight 115-114, 114-115 and 116-113 to Williams, Skelton believes he can take a lot into the second fight on 8 July.
"Without sour grapes I feel like I did enough in the fight previously," Skelton added.
"Straight after the previous fight I called for a rematch because I felt I'd done enough and I want to put things right.
"In the earlier rounds it was probably a bit rough and ready. The referee didn't take any points off me, but we're all human and it probably stuck in the judges' minds.
"Sometimes I just like to come and have a fight. Maybe it's a street mentality but it's taken me so far."
