Looks a lot better.
I tried cropping your photo.
I was going to suggest cropping some of the beach as well. Also, it might be worth playing around with cropping the sky too, as while there is some texture there, it doesn't add anything to the composition and it will move the horizon from the centre.
As for tripods, ballheads can work for landscapes, even thought they wouldn't necessarily be first choice. They are probably about the most versatile of heads if you shoot other subjects as well and they can help to compensate for uneven ground that the legs may not fully account for. To help with keeping things level, get a bubble level that goes in the hotshoe. Pan and tilt heads are the obvious choice for landscapes, but they can be quite limiting. I have a Manfrotto tripod and head, but they aren't always the best build quality and I have known people to end up with snapped catches, as they are made from plastic. I think Giottos tripods are much beter value, they are a similar price point to Manfrotto, with better build quality, as they use mostly metal construction, with less plastic. My Manfrotto 190 MF3 cost me around £180 about five years ago, yet my heavier duty Giottos 8241 was only around £200 I think about 3 years ago. When looking at tripods, the general recommendation, is to look at the load capacity and make sure it is around double the weight of your heaviest gear, remembering to factor in the weight of the head. Likewise, it is best to make sure the load capacity of the head is double the weight of your heaviest gear. This will ensure maximum stability, although if budget is an issue, you can skimp a little bit, as long as you don't esceed the maximum load capacity, but you will lose some stability. Also, make sure you can get it to go high enough without raising the centre column. This will be a particular issue if you are tall and want to shoot from a high angle, but if you are shorter or are going to be shooting from a low angle (which often works better for the coast), then it is a lesser consideration.
