That's a mean Mist Hunter. Well done. You've given me some inspiration. There is a Space minifig that bares some resemblance to Zuckass from set 70703, could fit with a bit of modification. Another minifig from 70701 could pass for 4-Lom with some modifications and paint.
The design looks cool, but what really got me was that amazing funtion of the windscreen openning to the side. That is absolutely genius and what really made me like the MOC. I kind of want to make something that does that now.
