Be patient with rendering. The extensions are getting faster to learn and use but keep in mind as it gets easier, everyone can do it and the bar gets bumped that much higher. If you’re on windows you may want to check out Enscape as an alternative or compliment to V-Ray as it’s designed for more ‘out of the box’ use.
Regarding your ‘straight-from-SketchUp’ view here…you could benefit from turning your shadows on of if you prefer not to show shadows, in the Shadows panel, check the box for ‘use sun for shading’. Also remember that good renderings are more than just software. Consider your composition, materials choices, quality of entourage (trees, people, etc).
