Dilettante Photography: Retrospective

Last time I got valuable comments and tips so I looked at my pictures in more critical way. I also tried to do better post production.This time I have choosen picture with objects in foreground to show more depth. I also have tried to make it brighter and more contrast. Technical parameters: shooted in RAW, olympus em-10, kit lens, iso 200, f 7.1, 1/250 s, 18mm, postproduction in RawTherapee + Gimp (on Linux) What do you think ? What should be changed in composition and in post production ?

It is my first post here. I'm new in photography and there are a lot of things to learn about technique and post production. Any comments and feedback are welcome. The parameters of picture: olympus omd em-10, with kit lens, iso 200, 1/50s, f5.6, 33mm. Post production - RawTherapee + Gimp (on Linux)
