It was his maiden campaign with the Rams, who finished 12th in the Championship, and he believes his move to an English club from Scottish Premier League side Kilmarnock has boosted his chances of being selected by Scotland boss Craig Levein.
“The manager always looks south for his players so I knew if I came to Derby and did well I had a chance”
Bryson added: "The manager always looks down south for his players for Scotland, so I knew if I came down to Derby and did well I might have a chance to get back in the squad, now it's proved right.
"He looks down south at players because it's a higher standard than the SPL."
The former Kilmarnock captain is eager to impress Levein ahead of Scotland's 2014 World Cup qualifying campaign, which begins with matches against Serbia and Macedonia in September.
"It's up to me to show what I can do for Scotland and then hopefully be involved in the qualifiers leading up to the World Cup," he said.
"I'm not sure how much he's watched me at Derby, so it's up to me to go there and prove in training I want to be there and, if I get a chance, to go out there and do well and show Craig Levein what I can do."
