3D lighting

Well guys i have been seeing some of you guys/girls posting your projects and they look good but you know me i must find a fault.And it is the lighting you see the lighting is suppose to compliment the drawing and i find in you all drawings they r either to bright or to dark you want to use the lighting to bring out the materials and make the drawing realistic and i am not seeing that.Hope u all understand what i mean and adjust the intensity to suit but out than that it is well done.I feel proud to know u have done so well in 3d and maybe we can transfer it to adt or 3d max
