I like your sketch! It’s a nice composition and a fun story.
Friendly advice if you want to practice drawing trees (or most things):
- start by drawing from life
- if you can’t, get some references, at least until you’re quite familiar
- focus on the thing you want to practise most = in this 5 min sketch to improve how you draw trees, you drew 10 fluffies, 4 trees, 2 gators, and 1 bird. You could have drawn 15+ trees and 1 fluffy, or just 1 more thorough drawing of a tree and then 1 fluffy.
