Hi, first of all i’m not an expert but i think:
- “gradient” color and background are outdate.
- Theme color is too “frozen”.
3.You can work a little bit on fonts and images preview
4.Search on themeforest in the psd category and see what is trend right now, to have some ideea how can improve your work. - I know is frustrating to be hard rejected, i personaly have 3 hard rejection so this is life.
As i said i am not in expert but is just what i see on your template(sorry for my english).
Have a nice day👍
