ande, the rendering and light level is ok. im just not a fan of the composition though. hope you dont mind if i say some friendly remark, to push you further.
that tree located on the third portion of your composition became your focal point. and its not really the most important thing here.
perhaps you should be careful more on the landscape. especially avoid on just randomly placing plants everywhere.
check also your background horizon. its a bit high comparing with your model's horizon
lastly, perhaps try to add contrast of texture.. your texture below (are all rough textures so its easy really for them to fight together.
i know this is one of your exterior and im one of your fan in terms of your interiors. but i know you could improve further and definitely you will even pass the caliber like FA (jsut the thread you have written on the other forum).
on the other hand my compliment in you in maximizing those 3d trees other than xforgs.
