hey dude nice work, howd you get that 'film' effect that you have on here. I hope I'm not being too unspecific, like its got a video effect for the colours, especially at the top of the mech where its got the orange, a hint of blue, but it looks like they're blurred with some kind of filter?... I've seen it in other speed paintings and i don't know how to produce that effect.
That's some nice work, I quite like the narrow colour range and the hazed out look, it definitely gives this piece a lot of atmosphere As someone mentioned before, it's a little flat, but I realise that is a speedpainting. But yeah, a stronger sense of space would be good to see in this, otherwise this is really good. It's cool how you indicated a face on the walker
