My model doesn't predict well (I guess)

I pretty much just copypasted the cells from the 00-is-it-a-bird-creating-a-model-from-your-own-data notebook and substituted with my own values. That was the result for my model:

Quite a difference from the original notebook:

Is this because my model isn’t predicting something as clear as the difference between a bird and a forest? My model predicts the difference between a kangaroo and a wallaby.

And is this really all the work we should do in the first class? Just run the cell ourselves and try our own images so that we just get used to it?
