LB Photo Realism is one of the most realistic texture packs for Minecraft on the PC. So it was only a matter of time before it is ported to Pocket Edition. And now, it has. But for now, it is only at 16×16 resolution, which might be a bit lackluster for those with powerful devices . Sure, it does not look photo completely realistic but it obviously makes your worlds look better, especially the grass blocks and water. There are still items like the sky and grass which yet have not been ported but that will likely be added in a future update.
