Well you're doing better than just keeping up IMO. Obviously a lot of effort this week.
At first glance I thought it
was a real car!
I also only saw grass when I looked at it . . . then with the realisation that it was a toy car I thought you'd photoshopped grass in from another shot.
To be able to make everyone look again at this shot shows how effective it's been - and a great bit of PP on the red blanket too
I'm undecided about the rain. It takes away some of the realism of the shot, but at the same time it covers up some of the tell-tale signs that it's a toy.
I think my issue with it is that it looks very 2-dimensional in the way that it's laid over the image.
Personally, I think I would have created a few duplicate layers of the rain. Moved them slightly so that they weren't directly lying over one another and then adjusted the opacity on a couple of them to give it more depth. I would also have masked out the car in some of the background "rain layers" to make it look like the rain was falling
around the car rather than just over the foreground.
(I'm not sure if I explained that very well, but I hope it made at least some sense - and given that I've never created rain in Photoshop I could be talking complete rubbish !!!!!)
