The my yesterday.

Yesterday, I went to the park near my house.
In the park, I saw a lot of beautiful yellow and red leaves lreafs. They ire falled fell  from the trees  and lay thick everywhere. (Note: the different coloured leaves can be referred to as autumn colours. )

I like a to walk, because when I am walking, I can find the cycle of the seasons, coloured leaves, flowers, the snow, sprouts, sunset, the wind, and so on.

How spending in the park my favorite, is that read a letter from a pen pal in Japan with a cup of hot coffee. My favourite time in the park is spent reading a letter from a Japanese penpal while drinking a cup of hot coffee.

This picture is of Narrowleaf Firethorn, it is called in Japan "Tachibana-modoki".
I taked took this photo by with my cellphone in the park.

Notes: As your later comment said, a number of spelling mistakes. Some of my corrections reflect UK spelling, US spelling may be different.

Verbs like taked, falled that I have corrected are examples of overregularization errors. That is you applied a rule that said add -ed to a verb to make it past tense. However English has a lot of irregular verbs that don't follow those rules. It is at once both an annoyance and the reason why  spoken English is so flexible. You don't have to be a good speaker to communicate, we can understand partial spoken patterns.

I liked the photograph, cellphone cameras can be very useful.
