Well this is definitely loads better than your other layout. I am happy to see that you went for some intense vertical gameplay. I have always enjoyed vertical gameplay maps (especially 1v1). I'm going to have to ask you to look at
Crescent and Solitude by Hipshot. They are great examples of what can be achieved through careful planning of vertical gameplay.
The main fault with your layout as it sits is the amount of stairs. I believe the vertical scale is a bit too large (as well as the scale of a few of the rooms) for tourney. The steps become monotonous and annoying around which to move. Perhaps consider a few more jump pads around the areas with greater amounts of steps.
I think the layout will need a bit of work, but the good part about the layout is that it is able to be worked on all throughout map production. The Red Armor and Mega Health are just a tad too close. If a player spawns near the RA he or she can grab it and drop down to get MH in mere seconds. A more appropriate location would likely be where the YA is right now. Being so far apart on a horizontal level will make it much easier to balance high value items. Consider centralizing the rocket launcher around where the mega health is. It may also be a good area for some small healths around the second level, I don't know. The layout should start falling into place once you have the structure of the map complete.
Anyway, this is leagues better than your original layout. I'm happy you decided to start it from scratch.
