creality ender 3 - what am i doing wrong ? Slighly failed prints

HI,

I have just purchesed my first 3D printer (creality ender 3) I followed the manual, and some youtube videos to set it up. I leveled the bed using a paper method, but still my "Test-dog" print dosen't come out great. I have seen some pictures of people printing the same model on the same printer, and the results were much better.

Extruder Temp : 200 C, Bed 50 C
Fillament: PLA 1.75

i would appreciate any tips of what i am doing wrong
