My first piece here! Hope I'm getting this right.
Gosh, I hate to have to submit when it still has so far to go... but the challenge theme was ancient vs futuristic and I set myself too much to do! So, so many hours have gone into this yet I have simply run out of time... but hey, at the very least I will get some feedback hopefully! Most likely with things I haven't been able to put in ;) but very welcome just in case! I know it lacks light, not sure how to put it, it's all saturated and grey if you know what I mean even though the shadows on him/her are quite dark.

Now, the creature may look prehistoric but actually it's the opposite. The story here is a future race was in the process of genetically modifying and putting together a new creature for some purpose, for some sort of war probably, when one of their subjects broke free and escaped through a portal, finding itself on medieval Earth. Unsurprisingly, the people fear for their homes and families and have declared war on the monstrosity.
The creature's glowing orbs actually create a sort of invisible forcefield around most of it but it is designed to take attacks from similarly large monsters (the future in this case being a time where everything on the planet it came from has returned to dinosaur-ish size) so funnily the arrows pass right through. It's thick skin is mostly enough to keep them out however, bar the soft neck flesh and it's eyes of which it has 6 (also four nostrils). One lucky soldier has managed to shoot the creature in an eye, and I've tried to portray the motion of it swinging its head up and away from the viewer in pain, helped by the saliva trail there I hope! Tips on that would be good if anyone has one! Struggled a bit with trying to get the neck to look like it's twisting, again if I had more time I might have fiddled longer. Apologies on the armour too, forgot my history ^^;
But yes, the fact they weren't finished perfecting it is evident since the gills are small, the horns too big, etc, all the bits and pieces that don't look quite right. I quite like the head really though, loosely based on a big cat. I remember having a reason for the horns to still be quite big anyway but I've forgotten it, I think they were supposed to have hollow areas for some purpose, storage perhaps, or riders?

If you got this far, thanks for reading! Have a great day! (and wish me luck in the contest, if it qualifies to enter~)
