People over exaggerate how easy it is to make a good tribal.
Look at Micho and BenDovers work, they make some pretty sick tribal textures.
Anyways, yours need some better eyes. Too much space on them for this style of tribal. When you use the brushes, make them flow together more coherently. If you need some pro help on doing tribals, try to see if you can get Micho or BenDover to give you some tips.
