Hey Dave! Lovely art! This is beautiful. I love this!
I have some minor things I noticed, since they will be shown only once and quick in the game, they are very minor and probably a bad return on investment to pursue. But still, thought would mention.
The first shot, the rain though looks a bit wrong? This is a
quick reverse close-up from Singing in the Rain (around 1:42). In the gif the rain is falling from up to down, but from the angle the rain looks to be going horizontal, instead the drops should falling in front of the camera.
I love the train and the dude meditating.
On the last shot, I don't know how you are doing the panning, but in the
gif the movement doesn't look smooth. If the game is 60fps and you are tweening y position of the objects/GUIs it will probably look smooth, but in the
gif it doesn't look smooth.
