Good to see you persevering with the Elm Reg, not the easiest of timbers to obtain a good finish on.
Based on my personal preferences I would make a few comments; please do not take these as rubishing your efforts, just pointers as I see it from my limited turning perspective.
I would have aimed to form the internals of the sides so that they gave the impression of being thinner if not in practice, curvature of the top lip and sharper edges will do this.
I think the internal base detail is superfluous, if used as a container they will not be seen and may be difficult to clean if collecting debris. They also detract from the natural wood figuring in my opinion.
The side decoration is difficult to see, and obviously you gained turning experience in forming the beads but beware of making the piece look too fussy.
Try not to leave circular tool or sanding marks in prominent places like the internal base area, often a little hand sanding across the grain is more effective in eliminating these than sanding with the lathe rotating, although in this case with the decoration in place this would be a little more difficult.
Once again please do not be disheartened by these comments, they are intended as guides/pointers as I see them for your next piece.
