New organic sculpting in zbrush and LR in game model

Im coming back to one of the models I didnt finish yet since I a have to deal with a full time job and my 3d passion , trying to bring it more into the realistic side to this model lets see how it ends up ......

 I have done several adjustments on this bust to improve it so I could say it took me around 2 weeks to get it done , 3 hours texturing and half an hour to set up the lights plus another half an hour to composite it in photoshop

This is another test I did to create a game character the completion time: 3 hours for retopology, 3 hours to texture in photoshopand 1 hour to set the mesh in marmoset .
