Amazing stand so far man. Ive been taking woods in my high school. Our high school is ranked 1st in Illinois for woodworking. I dont know if anyone knows this but every year theirs a nationals for woods for the whole country and someone from our class always represents Illinois.
As for the doors, I dont know how much you paid for those but if you want to save some money on them and you have a router all you need is a stile and rail kit.

They look amazing. if you have any questions on them you could PM me. and for the panel to put inside it looks like they just took a piece of plywood and cut it to size to fit in there. Not a bad idea. There are some sets out there that offer another bit to use on solid stock to make the panel for the inside (

Just something for the future depending on how much it cost for those doors to be made.

You may also need a router table too. Sorry
