Thank you for the crit and I was thinking of using a diagonal line for the light on the door but I wanted to create some curves but looking at it now I think a diagonal beam may have been better suited.

I don't really see anything majorly wrong with this piece, but It's a bit harder to crit a two-tone with backlighting. I can give some suggestions that you could try(not sure if it will impove it).

Instead of the lighting on the door looping around like an oval, have the light go down diagonally all the way. The dithering looks unneeded and makes it a bit rough and overused. The dotted lines for the outline of the door looks good though.
