Hey, thanks for stopping by my sketchbook!
I love the whole sc-fi+inca culture project idea and you're dishing out some sweet concepts for it! Among all of them the stripey llama creature really pops out (because it's fuzzy and slightly grumpy looking with lovely, natural colours and great brushwork), along with the third vehicle (because the design kind of makes it look like this giant insect, and because the metal is so beautifully rendered). One thing that hits me about the environment WIP is the perspective of the face on the arch. You might wish to turn it somewhat away from us to the right in order to make it line up with its foundation; the viewer seems to be standing slightly to the left of the arch while the face is turned directly towards us. Great work though, can't wait to see it finished!
