I should have added the intermediate books are far to advanced but the beginners lacking extra detail

General impression: You should solve tactics 24/7. Training positional chess or endgames are useless without being able to calculate. You should use classical openings. The (Hyper)Modern openings do need some positional insight. Move 11 instead of B:P you should have played N:B. it would have opened the c1-h6 diagonal. Move 16 B:d6 is an error. N:d6+ would have won a took either via d6 or N:f7 would have been a nice move. Move 21 R:R would have avoided the mate in 2.
"... for those that want to be as good as they can be, they'll have to work hard.
Play opponents who are better than you … . Learn basic endgames. Create a simple opening repertoire (understanding the moves are far more important than memorizing them). Study tactics. And pick up tons of patterns. That’s the drumbeat of success. ..." - IM Jeremy Silman (December 27, 2018)

"... In order to maximize the benefits of [theory and practice], these two should be approached in a balanced manner. ... Play as many slow games (60 5 or preferably slower) as possible, ... The other side of improvement is theory. ... This can be reading books, taking lessons, watching videos, doing problems on software, etc. ..." - NM Dan Heisman (2002)

"... If it’s instruction, you look for an author that addresses players at your level (buying something that’s too advanced won’t help you at all). This means that a classic book that is revered by many people might not be useful for you. ..." - IM Jeremy Silman (2015)

Looking quickly through the game and this is what i dont like:
6. c3
7. Nbd2 (Bg5 seems better)
11. Bxe4
20.Re8+ (I dont see a purpose, seems like there should be some useful move, maybe I would like to sto Rd2 from black so I would consider Nb3, other than that also Ne6, Kf1 might be worth cosidering)
thank you all for your helpful advice , I have been doing alot of puzzles and switched from rapid to blitz but found I went backwards so have resumed playing rapid, it wasn't my best game to post but saw that it's better to get advice on a loss, will go through the moves you picked up and have a look at the reading material, again thank you.
