Well I don’t think there bad but. It just needs some pop or something. Like something to tell it’s yours like art wise. For the custom poses, I would just think about “is this realistic?” Because a lot of them look cringey because they don’t look natural. But overall it’s a good start!!
If you’re looking for criticism, here I am! (Noah’s fence of course.)
In your character edits, the pictures are kinda pixelated! I suggest using larger screenshots of the characters. In your drawings, the shading pops out more than the drawing. The shading for the skin also covers some of the eyebrows, lips, clothes, and stuff like that. I suggest shading the clothes and adding highlights! Try to lower the opacity of the shading as well.
Anatomy-wise, some of the arms and hands are too small and too big. Some of the poses are unnatural and awkward, try looking at references!
Overall, you have potential! Your art is okay but needs some work. Try looking at tutorials!
