Not bad at all. How does it attach to the tree? I used to weld my own tree stands out of old bed frames and even thought I thought they worked well I found they were too heavy and very hard to put up. I think yours might also be too heavy. As long as you plan to put it up and leave it for most of the season then they are fine but not something you will move around much.
You might try driving two or three nails through the bottom so they protrude towards the tree so when you attach it the nails will dig into the tree. Just a way to make it more stable. When you attach it use a good strap or chain on the top and the stand will be solid once the nails inbed in the tree.
Looks good to me.
