You still have one Skill Point you haven't used. I reccomend you spend it on the other attack you get in your giant form, since they're both powerful, and if you have two, then you can use the other while waiting for the previous skill to cool down.
I'd take some points out of the buffs in the first tree (well personally I would take all of them out lol), and use them to get and upgrade Confusion and Disastrous Blow since they are major pvp pwn skills.
Also in the master class tree, get the constitution passive buff instead of EP. Since LP is your main focus in a Namek Warrior, not EP.
Sacrificing some buffs (in the first tree) to upgrade Cyclone, Dragon Strike and Giant Ground Wave also wouldn't hurt either. In fact I'd even remove points from the passives since these skills are so damn powerful when maxed.
