I've recently dived into Heavypaint (such a brilliant app).
I've joined March of Robots this year and thought I'd share some recent mech sketches I've done. These are relatively fast (for me at least) sketches that took about an hour to compete. It's a great challenge to come up with a new design every day in a limited amount of time.
At this point I can see a difference in my workflow and how I've managed to be less precious about my designs, which is great, because it's so easy getting caught up in the details and noodle away. So all in all this is a great exercise for me.
I'll post some more mechs as I go along and in the end I'll post a summary of all the 31 :)
Thanks for looking!
