Hello! I need ideas and advice!

Hello! so these arent really details, but I would like detail ideas for this build! im currently working on it to improve my terraforming and custom treeing, I would really need advice for the tree though! im happy with it but I feel like the top part is useless and theres too much leaves but idk. Should I try to add dropping leaves with candles on top of the particles? Also if anyone knows what would be the irl tree species that would be the closest to the one I built?

I would like to say that I was too lazy to call upon my imagination and just tried to remake differently and in my way Bdubs base fron hermitcarft season 11(so i could try and get a better grasp at this new more realistic build style im pretty new to).

anyways thank you guys very much and have a wonderful day!
