The young stand-off put in a man-of-the-match winning display as the Warriors maintained their 100% start to the PRO14 season. Along with scrum-half, George Horne, Hastings was at the centre of much of Glasgow's best work in Wales.
Speaking in The Herald, Hastings said: "It was my first ever man-of-the-match award, so I'll take it. I don't think I had the perfect game by any means, so I will just go back next week and keep working.
"I enjoyed playing, I enjoyed starting, I have made no secret of that, but there was a lot to improve on."
With Finn Russell moving to Racing 92 at the end of the season, Hastings is determined to make the most of playing with the current Scotland outside half before that happens.
"Finn is a good guy, I get on with him really well and I am enjoying learning from him. I think for the rest of the season I will just pick his brain as much as I can," he said, having made the move back to Scotland from Bath during the close season.
"Definitely that will be something for next season, there are always opportunities, so making that place mine next year will be at the forefront of my mind for sure.
"I made the decision to come back up because of potentially more game time and I have been getting a bit more so I am happy with that.
"Scottish rugby is in a good place, it has been on the rise for a few years and I think things are finally starting to click now. Gregor is doing a good job as a new coach, and they obviously have high quality coaches with Richard Cockerill in Edinburgh and Dave here in Glasgow so it is on the up.
"I would definitely want to be part of it, you want to be part of a winning team.
"The first try was a funny one but thankfully it just opened up for me. We do have a lot of depth and the younger boys seem to be stepping up so that is good news. I enjoy playing with George, we both like to run the ball so it is lovely."
Glasgow coach Dave Rennie is likely to rest his international contingent after their impressive November, which may mean another opportunity for Hastings to impress when they face Cardiff Blues at Scotstoun on Friday.
"Again we have a few options at outside half, but he has been really good," said Rennie, when asked about Hastings. "He is quite deceptive, his ability to see a bit of space in behind, he did well for a couple of tries and he is growing in confidence - I thought he was really strong today.
"Our job is to create depth, we found out a bit more about some of the guys today and they would have learnt about themselves as well so that is exciting I reckon.
"It is a case of managing those guys anyway. The Scotland guys won't be available next week, they've had three international weekends so we will make sure that when they come back in they are raring to go. We will tell them to go away and work somewhere, they will have programmes to work on."
