Looking for criticism and help to improve

[Omicron White]

I've been looking around Facepunch and other places for guides and ways to learn how to be better at posing and scenebuilding close to a year now, but I don't think I can learn anything else just by myself. I'm hoping I'm posting this in the right place and all, but I'm asking for criticism, tips or whatever else on how to improve scenebuilding and just general criticism on things I've done so far
(I'm sorry if this is the wrong place to post or something, I'm a bit new to this).

This is a collection of most of what I've done in no particular order:

Any sort of comments or help improving is greatly appreciated, thank you in advance.

Those are pretty damn good for a (forum) newbie. That scene with the forest especially.

I could probably spend some time picking out mistakes but honestly, they're all good. I prefer the top 6 to the bottom 6
