Deleting table the db get bigger...

Guys, I'm wondering how can be possible a fact like that. I got a database test, the size according the query below was DatabaseName TestD

Row SizeMB 121187

LogSize 43

DBSizeMB 121230

DBSizeGB 118.38

 I deleted practically all the table but two tiny table and now the size is:

Row SizeMB 121187

LogSize 55

DBSizeMB 121242

DBSizeGB 118.40

More...!? How can happen?

SELECT
