Starters

Good luck with your company! Best Wishes

Nobody likes a critic, but you have to learn about furniture design and proportion. Start with books on old furniture and furniture design. Then work on your staining technique. Nothing says amateur more than seeing the barber pole effect on the right door of your last picture, 1/2 light 1/2 dark is caused by the oil stain and technique you are using.
Good luck and read up.

Agree with last comment. Oil stains suck, especially Minwax... worst stain on the market. But you could have avoided the dark and light staining in those doors & exposed back panels if you used a whole piece face...
( Veneer ) not plain sliced veneer on your 1/4 oak plywood, A1 or B2 grade plywood. cost a little more, but finishes a lot nicer!
Wish you the best...not an easy living!!!
