Your voice is very nice, but your english diction needs a lot of work, but you are.... Polish? so it makes sense that you're having trouble with the language - there's a few sounds in english that don't exist in polish.
The most obvious and distracting one is how you pronounce th's. It sounds like you're saying 'djh,' like 'anodjher' instead of 'another.'
Try making a 'sssssssssssssssssssssss' sound - just keep holding it until you have a pretty good idea of where your tongue is in your mouth/what shape it's in. Now, touch the very tip of your tongue against the bottom of your top row of teeth, while trying to make that 'sssss' sound. What SHOULD come out is the real 'th' sound.
When you're singing it correctly, the tip of your tongue should lightly brush against the back of your teeth, really quickly.
If that doesn't make sense, I can demonstrate with a sound recording if you'd like.
