If you wish my honest opinion - I like first "entry". Simplicity and calm colors are what I liked.
However, that's my personal taste. I can't tell whose work is better (more professional) simply because art is such a subjective thing. What one can admire, the other can hate.
You should be competing. But for your own good. Without insults, without words at all. Show as pure art race. With matured authors behind it who can improve by reflecting on themselves.
You won't get a trophy, nor any reward. Only experience which is vital part in your hobby/work. Thus stfu and please our eyes with extraordinary works. Make us "artgasm"!
