Wild cherry

I have had this Prunus for a few years now. Now was a good time for the first defoliation of the year. I am planning to do it one more thime this year.
Below you can see the quick development of the tree.

This is how it looked like more then a month ago when it was flowering.

Till now I lefti it grow freely and now performed the first defoliation and styling of new branches. Quicklly getting to final form.
