Much, much better.
One small thing...
The stand is built from a triangle wedge with a "rim" placed around it, from the looks of it. The problem is that the "rim" does not line up with the triangle perfectly, and it really should.
This would be most easily done by creating a cube, deleting the top and bottom faces, then grabbing each vertical set of corner vertices (one vertex above the other) and moving them so that they line up, in plan, with the corners of the wedge shape. Make sure you're using snapping to allow you to snap your vertices into place exactly.
Also, think about whether your poles really need to be perfectly cylindrical. Think about perhaps making them 4-sided or 6-sided. This greatly reduces the poly count and makes texturing a little bit easier. You can also do what is called "softening" of the normals of the faces, which means that an angular object looks smoother by changing the way light reflects off it.
General Advice:
Remember that a lot of stands are quite similar, so you might not have to remodel everything completely. By taking an existing stand and modifying its proportions, it can be a good base to start another stand from. This is easier to do if your models are tidy and well put together, so paying attention to detail over things like vertex snapping really is important.
