Let me try and give you some detailed feedback, as I see it. Others will then have a chance to agree or disagree.
Let's start with the foot:
1) I think the diameter of the foot is OK, but the rise towards the stem is too steep and also has no curve.
2) the stem is a little on the thick side (but not much)
3) The bottom part of the bowl/box/form is UK, but on the picture it looks like the curve has a bit of corner in it about a third of the way up from the stem.
4) The top is where the real problem is. The very top is flat. This could be a design decision, but the curve where it goes around towards the vertical part of the shape is just totally undecided. It's neither smooth flowing, nor is it sharp(ish) corner. And that really spoils a lot of it.
5) The lid is also flat. Again, could be a design decision, but it's too thick to look elegant, and its corners have been rounded off (probably by sanding). If you want it flat, make it thinner, and make sure the 90 degreee corner is precisely that, with only the sharpest edge taken off with a 400 or 600 grit.
6) The finial: In general just too many straight lines. Having said that, it could work if they were all really straight, and somehow symmetrical or aligned, but they are not. I think the biggest bummer is the change in direction of the straight line about a third of the way up on the onion part of the finial. At the very top the small little bud looks OK, but the curve towards the top seems interrupted, and the curve at the bottom is definitely interrupted.
7) The straight grooves were probably made with a parting tool, and in my opinion that really only looks good on a honey dripper.
Don't get me wrong, I fully understand how much work has already gone into this, and I do appreciate it. I'd like to say to you that in terms of actual work there are small changes here that would make all the difference. Some of them could still be done, some depend on whether you have enough material left (3mm is probably too thin) and whether the two pieces can still be mounted in some manner without breaking them. Apologies if this all sounds harsh, but I believe honest and detailed critique will be worth more than not saying anything.
