Feedback on Guided Project: Bike rental predictions

Hello DQ Comunity!
I just finished this project and would like to see any review. I’ll be glad about any comment :wink:

Overall I found a best MSE=1582 with random forest. Since this is squared error, the error ist about 40 bikes count. I concluded that this error may be too high, depending on the context the prediction is used. The ground for this conclusion is that the distribution shows that most of the values are small values (for example, less than 100). Am I right?
