What started as a sketch

The plan was to just draw Murusraptor with some soil or so to walk upon, but the soil turned into rocks and then environment appeared. It's about half an A4 big (so actually an A5) which is a bit sad now that it's done, I could've put more plants and hidden critters in it if I filled up an entire piece of paper.
Anyway, I'm not so sure about the dense vegetation and the species of plants since Late Cretaceous Patagonia was quite dry afaik so this'll probably be a creek in a valley during the raining season or so.

So, Murusraptor barrosaensis, that huge megaraptoran from Argentina, 93-89 million years ago. It's know from an incomplete skeleton from one immature specimen that is estimated to have been about 8 meters long if it was fully grown. So, this is the biggest megaraptoran we now have yet, ignoring the "Ridge Ripper" from Down Under, right?
