I love this to the point that I want to live in it! How bad of an idea would it be to live there? I mean this looks like a pretty cool place to hang out if you managed to get some electricity, water and heating.
this is pretty sweet, but i think you should go in an add some depth to the painting. Its hard to really get a scale for how large the engine thing is in the background. Add some atmosphere in between the rider and the structure, make it lighter, something to show distance.
