If you want to improve in terms of competitiveness, then you need a second Daemon Prince.
Additionally why take melta-wielding Havocs as your heavy support? Okay they're supporting your advance, but with three squads of chosen up front, they seem overkill to me.
Also taking so many meltas (you've got 23) is great at short-range, but you've got to get there first. Even with the Plasma Guns you're still rushing across the board hoping not to many of the Rhinos get shot up.
Remove the Havocs and stick in five Obliterators, allowing you to provide long-range support to your charging Rhinos.
I like the chosen squads, just be careful when deploying them as there are several armies, notably Tau, that can really punish smaller squads caught in the open.
