How to make My model Render realistic?

What would be the best way of going about rendering this model to make it look realistic, i would like to say im a good modler but ive never made anything realistic, due to i have no clue on how to… or even if my model is able to look realistic, anyways heres some renders

Lighting, environment, and shaders are where a great deal of realism comes from. The model looks good, but it would probably behoove you to read up on cinematic lighting and play around with some different environment maps.

At the moment your materials seem to have no reflections and the model thus looks very flat. This is either because you haven’t set up lighting or you haven’t used materials that have reflections. This book is a good read

And yes you look like a very good modeller =)

the final render was this :
