Very nice design, great (and funny) to see how you got there too.
I'd have to agree about the stance, well the leg on our right in particular. I think it looked better at the lineart stage. This might be because, as it seems the main light source is above, that leg would catch more light than the other as its bent.
A couple more minor crits, the forearm to our left looks a bit flat, I think the cylindrical bit could taper a bit towards the bottom.
Also, the colours are lovely, but that very grey midtone really jumps out on my monitor, I think the saturation could be boosted on just that one colour to match the rest a bit.
Other than that very nice indeed, I really love the sparky stuff.
