The defender featured during the Championship side's 2-0 friendly win over Nuneaton.
The 27-year-old completed a loan move to the Blues from Championship rivals Derby County towards the end of last month, and has been selected on the bench for Gary Rowett's side's games against Bristol City and Sheffield Wednesday.
However, he has failed to get on in either encounter, meaning that his involvement in the friendly with Nuneaton was his first bit of action for the club. And Beale was satisfied with what he saw during Shotton's 45 minute stint in the 2-0 win.
"I thought he looked strong, he read the game really well as well. He won his headers in what was a competitive half," he told the Mail.
"He strikes me as a really mature and good professional.
"He did everything in the right way, was a good example for the young lads and did his chances of getting into the first team no harm, I am sure."
Having only made a handful of appearances for the Rams before leaving for St Andrew's, it is not a surprise that Rowett has not thrown the new arrival into the first-team straight away, especially with the club performing so strongly in the Championship.
Before the defeat to Sheffield Wednesday in their last game, Birmingham had kept three consecutive clean sheets, and so Rowett may have been wary of introducing his new signing into the side too early, and upsetting a balance that had been working so well over previous games.
However, if the former Stoke defender can continue to impress when opportunities come his way, it seems likely that it will not be too much longer before he is appearing regularly during his loan spell.
