@MasterQ32 : It's hard to see some 10 or more textures, i just see one grey texture, with strange green things on it. Some AAA games uses terrain chunks and some 5 multi texture, each chunck can have different textures and common ones for merging (Oblivion game) !
For your screenshot : it's very very grey, it looks strange, far from some natural terrain.But if you don't target making a game and just bring tehcnology it don't matter !
You should search for better textures : try cg textures , and put real better lightening instead of flat look and light !
