Gday Byren! Some nice work you’ve got here, I’m impressed with your work ethic above all. In regards to your latest piece, a problem I find with it is the shading of the stairs.
The upwards faces are being lit by the red lightsource off to the right, but the vertical faces of the stairs which are facing the lightsource are kept in shadow. I reckon it should be pretty much the other way around.
Along the roof, as it gets towards the mouth of the cave, the colours sort of lose red, and then gain red again right towards the end of the mouth. Just seems a little strange, I’d probably cut the red back there.
The girl seems overly bright, and the highlights on her look too yellow, I get the feeling like they should be more red, and her shadows should be darker, basically. It feels like the two figures should be casting shadows on eachother, him on her legs, and her on his cape, maybe.
For the mountain in the background, towards the left edge of the piece, it seems a tiny bit bland, just being that straight up green. It looks to be rather steep there, maybe the green could give way to a desaturated grey to imply a rocky slope, or something.
Towards the top of the stairs, on their left edge, theres some somewhat strong green highlights, then more to the left on the bare stone there’s an absence of any continuation of that light, which seems a little off. Maybe try adding similar highlight there to make the stairs seem more a part of the stone.
That’s about it for my crits, keep up the solid work!
