In introduction, you could mention some fact about rainforest to make it more impactful such as most diverse land-based ecosystem/area of tall evergreen trees receiving high amount of rainfall etc
In distribution, I think you have just mentioned tropical rainforests, however, both temperate and tropical rainforests should be mentioned- also both could be shown on the map. Temperate rainforests are found near the coastal areas in the temperate regions in both hemispheres- found in the Pacific Northwest in North America, Chile, the United Kingdom, Norway, Japan, New Zealand, and southern Australia. Tropical rainforests- between 23.5°N and 23.5°S latitudes. You could add areas such as western and central Africa, western India etc other than what you have mentioned.
Characteristics part is fine, some detail could be added such as amount of rainfall (2000-10000mm), temperature range(20°C- 25°C). Also, you could talk about soil and demography.
Points mentioned in threats are also okay, you could add things like deforestation, mining, cattle ranching, climate change etc
Try to use flowcharts or hub-spoke diagrams for some parts of the answer to keep it neat and clean, presentable and including more content.
Conclusion is missing.
Keep practicing. 🙂
