Hi, just looking at your PCB pattern, it might be wise to widen the track width on the supply and output tracks to the stepper from the L298, you have sufficient room.
Add some bypass and filter capacitors to help with regulation and any noise from the stepper.
I also noted the silkpattern gnd and +5 does not match the bottom layer text - 5V +.
I don't know if this is your first PCB but its usable, some more use of the top copper layer could have helped your layout.
A good way to learn and good to see you have got this far before requesting help, well done.
Good to see you have room for a heatsink on the L298 if its needed.
Good project...Tom...
