LM298-Motor Drive PCB

Hello, I´m doing for the first time in my life a PCB board, I´m trying to build a motor driver, I will be using 2 DC motors. I finished doing the Layout and PCB. I couldn´t find any mystake but before I order some PCB´s would some one more experienced with PCB´s layout be kind to take a look at my first PCB Layout ?

Thank you very much for your time and attention

Edit: Here are my Gerber file if any one would take a look Gerber_PCB_Receiver_20190523030711.zip - Google Drive
