Technical Problems

No problem with your English. Use your native language, there is probably a good translator available.

Apart from what @jacquelingphoto2017 said, the building is great, but the angle you chose to take the picture distorts a lot. Buildings like this are best taken from more front positions if you want showing the whole building. 

However, as this is a quite iconic building, you should make sure to have the authorizations required for publishing the pictures for commercial use. Without that you may still be able to submit for editorial use, however, Adobe is quite restricted here.
