Welcome!
Your experiences are aligned with so many of us on this site-
I too built the Cutty Sark, it's long gone but the brass plaque you could send in to have engraved with your name is still stuck to the wall in my parent's garage, (the model went into the trash many, many years ago after I'd left home in for the US Army).
Coming back to the hobby just about a year ago, I was delighted to find all of the amazing tools and COOL stuff, making building and detailing so much easier, if not actually a bit more difficult as you tumble down the rabbit hole of details and develop skills.
I think you'll find this site is full of incredibly friendly and VERY knowledgeable folks, who are in a similar boat.
I can say, be patient, don't expect perfection- let your skills and knowledge develop and don't be too hard on yourself.
Share your builds and most importantly have a blast!
