Get rid of imperfections on my cured resin like wrinkles / clouds

Hello everyone , iam recently having troubles with an not nice&even finish of my resin oceanpaintings! My room temperature is 20C* with a humidity from around 50% – don’t get it what’s wrong , first I was thinking iam overtorching or too much heat with the airgun – ooooor iam working to slow and it starts already during but not still not sure about that..at least the first 10minutes after working on it, its pretending to have a perfect surface 🙄 Btw iam using resin pro mixing ratio 100 : 60 & here is a link with a picture of my problem https://abload.de/image.php?img=imageqzkkg.jpeg Thankful for every reply , peace out ✌️
