Below is an image I did this weekend. I got the job Friday morning and I had it for a client meeting Monday afternoon. I am happy with it!
Really dark image…
I like the car wash setup…
Nice work. You might want to make some highlight/Shadow adustments in PS. The image is a bit dark right now as previously mentioned.
You do a region render to the right of the door? I see a line where the shadows are a tiny bit diff. Anyway I think it looks great.
Good work…bit of variation in grass colours would help a bit I reckon. The dog looks a bit plastic..is it the one out of scrubs that JD and Turk have in their apartment ? 
Update
Here is a little update.
Lake Home
The client has a red Nissan and a yellow lab. I purchased both from Turbo Squid.
I just got word this morning that we landed the job so the image impressed them. The owners were about to hire a local builder, but one of our guys, who is the owners golfing buddy, got word and asked him to give us a try. We met with them Monday night and they signed today!
If you don’t know we are architects and builders. The perception in our area is we only do multi-million dollar homes and commercial projects The is a $450,000.00 home so he thought we wouldn’t be interested. We probably will not make any money, but we will keep some people working.
It looks better…maybe is my monitor but the shadows seem too dark
if you use environmental light dafault(Light blue) you get dark shadows but if you override it with vraysky will look more natural and lighter.
I would change the color of the grass as well, it’s too uniform and that green is pale
Lake Home
it looks good on both my monitors, but it does print dark. I used an HDRi in the environment light, but I’ll try with the vraysky next go around.
