'Good light' is all relative.
You're stage of image is way too early to call it either good or bad light. Way too early. As it stands, it's very very standard light for this stage. As it stands, your light is super strong and contrasty. This will obviously change as the scene/materials develop. One gets the impression 3d archi rendering is brand new to you. Dont worry, keep on going and ask questions later :)
