That looks cool :) I feel like I should check SketchUp out again, I remember looking into it once as I thought it might be quicker to create buildings with it than in Blender but I had so much trouble doing anything I eventually just gave up, I'm dumber than a 10yo child aaaahhhh XD
Sketchup gives you nice backgrounds or means to create nice backgrounds too or did you do that in something else?
The basic SketchUp have very limited tools compared to other more professional ones, however there are a lot plugins (that I never used) that could rival even the more professional ones. I like SU since it's the least complicated among the many 3d softwares, IMHO.
The final render is done outside SU.
P.S. my colleague's 10yr old son modelled a small city using SketchUp out of fun (some details were taken from SU warehouse but the majority were original), unfortunately I don't have a copy of the file.
And that's how I got into SU, lol. Challenged by a kid...
That's one way to get into things XD
