This is to date the most realistic shaders pack for MCPE. The light of the sun and moon shimmers beautifully when reflected on the water. Shadows have been massively improved and so have the sky and the Nether. The hype for this is real and you should definitely give it a try if you want to experience a more realistic version of MCPE.
