The winger lined up against MK Dons in place of Demarai Gray and responded with a sound display.
After overcoming initial nerves, Solomon-Otabor - who turns 20 on Saturday - imposed himself and made several trademark sorties to cause problems for the visitors, using his pace and power.
"It felt great," he enthused. "At the start I was a bit nervous but as I got into the game I felt good.
"Second-half I started sprinting more and stuff like that, running in behind, and just attacking the best I could.
"The crowd roaring, getting behind us, it was just a great feeling to be out there playing in front of so many people.
"In training everyone works hard for places so if the opportunity like this comes again I will take it, 100 per cent. Definitely I would like to be involved more.
"All the manager has said to me is 'well done, let's hope it's the first of many' so that was all positive."
Solomon-Otabor had earned his call up after showing what he could do in 12 previous appearances as a substitute. He made his first Blues bow in August, against Gillingham, in the Capital One Cup.
The Londoner came to the Club in 2012 after Blues spotted him in exit trials after Crystal Palace decided not to offer him a scholarship.
Manager Gary Rowett commented: "Viv was probably a little bit nervous at first, he was trying too hard, and he was up against an experienced player in Dean Lewington.
"Perhaps he played up against him too much and I said that to him. I said 'listen, your biggest attribute is your pace - run. Run, movement, make it hard for him'. Second-half he did that and worked incredibly hard.
"It's all part of the learning curve. We felt he was worthy of a start because he has showed so much coming on the pitch as a substitute.
"He tends to do what we ask him to do. He's a very selfless player and also Demarai Gray had a migraine and felt a little bit rough on the morning of the game. So we felt the right thing to do was go with a fresh player on the wing and keep Demarai for if we needed him the last 20 minutes."
The attentions now turn to Saturday's game versus Brentford at St. Andrew's.
Solomon-Otabor said it needed to be more of the same from Blues.
"It was a great result after the game on Boxing Day against Sheffield Wednesday. It was good to bounce back like that.
"The manager asked us for a big reaction and it was a good performance from the lads.
"We created a lot of chances. Clayton Donaldson hit the crossbar, Demarai Gray hit the post, there were others - everyone was at it."
