New recruits Luke Narraway and Ryan Lamb, both signed on loan from Gloucester, impressed when they were brought on as 50th minute replacements and the way Bees battled back after they went 19-3 down impressed Maynard after recent disappointments.
"I thought we showed a lot more character than in some recent performances and that we were a little unlucky not to win or to come away with a bonus point," Maynard said.
"Luke and Ryan fitted in very well and they showed in the short time that they were on the pitch that they are quality players. The forwards also dug in and although we were disappointed with the result, I think that we can take a lot of positives from this game."
Penzance, coached by former Bees backs coach Jim McKay, built on an early try from England sevens international Rob Thirlby to open up a 14-0 lead but the Bees pulled back a penalty through Tim Walsh.
But the Australian fly-half was off target with two more first half penalty attempts which would have reduced Penzance's lead to just five points. The turning point came when Wes Davies scored shortly after the interval despite the Bees' claims for crossing.
Instead of moping, the Bees rolled up their sleeves and battled back with the introduction of Narraway, Nathan Carter, Ed Orgee and Martin O'Keefe bringing fresh vitality to the pack.
It was England Under-19 fly-half Lamb who set up the Bees' try with a neat break and flat pass which flanker Narraway gathered to power over and Lamb added the extras.
Further Bees pressure failed to bring thepoints that would have secured a bonus point and the long trip home was made without tangible reward.
