well since ur just starting off i cant rlly say that its horrible
1. u should change the size of the txt and try to keep it simple because the txt is taking the focus away from the render
2. make the render stand out more and also i could see the eraser marks around him and im guessing thats from a c4d or something u put over ur render and it looks weird so u have to blend it more by tryin to smugde
3. that blue part over ur txt doesnt match at all and its kinda random there
overall since u are a beginner i would give it a 2.5/5 just keep looking at those tuts and get better
