Yes , you will look better if the photo has a normal size.Like as an example , the photo with the lamp over your head.

The lamp is disturbing and it also adds more space to the picture.So , the size of the photo is not realistic , compared to your own figure , in it.Crop the lamp out of the photo.

Furthermore , it is also good , to not cut off , parts of your upper body.
Show your shoulders , arms and hands.Look relaxed , you want to show something from yourself , and not to hide something.

And if possible , try to be a "bit mysterious".The proper dresses may help you with that also.

The photo , in the black dress , against the black night sky ,is making me think , that you want to disappear , in the black night.

Brighten the picture a bit in photoshop or similar software.Or make a new one.

I hope this helps
