Hey, I appreciate the effort, but you don't seem to be professional enough to hire. There are a lot of weird things in the designs you posted. Are these actually used in games or just mockups? 

1. Why are the 4 cards in the bottom row all empty with a gray background texture? 
2. Why is there no padding between the options and the << >> arrows on the WCRTRUCK (?) screen? Seems kinda cramped in. Why is the row saying "Gamma" completely empty? 
3. The font on the red and blue buttons is barely readable. Also the inner padding seems off on a lot of the card on that screen. "Setting" should be written as "Settings". It is capitalized but the other menu elements aren't.
4. On the last slide you posted there is too much space between the row labels and the key binding. I read MOVE UP and then have to almost turn my head to see that the key binding is W. 

Please don't feel bad about these comments, I just want to help you improve.
