Looks to me you have some shadowing issues, On the thumb and parts of the knife.
Idk if what you are using is similar to what I can 3d model in, But you should use triangular plane's to fix that.
To explain - A mesh made of triangles, when bent or folded will fold along the vertex of the mesh.
But square planes can fold along the actual polygon face, causing the lines and shadowing effect, to fix you need to break the areas up that are shadowing in to triangular faces.
Good job though, I like the berret but it looks more like a wooly hat.
I have not looked at how to make these items yet but plan to soon, What modeling program do you have to use?
Hmm, the beret is probably the best thing here, but I'll g=tell you the few things I noticed:
Fez: looks nearly perfect, nicely proportioned to toris head and everything. It would look much better if you used smooth shading before exporting it (just click smooth instead of flat in blender, idk about other programs if you use them)
Beret: Looks awesome! Only things I can say is that its not very beret-like, it looks more like just a knit cap with a very large ball thing (idk what theyre called lol). beret's are more flattish, which is the entire style of the hat. It looks like you also managed to smooth shade the main part while leaving the round bit flat and angular... It seems very high poly too, which isn't at all an issue if you and others are just using it through your custom folder, but it'd be good practice to try and keep poly counts around 1k, especially if you have any ambitions of being in IF.
Hands: not perfect, but a very decent try. Certainly turned out better than my attempt ;)
Dagger: I really don't know what to say about this... From the pictures it seems just kind of bad. I can't say anything you can do to fix this other than try again. The blade is a bit misshapen seemiingly, the back edge of the blade being the main issue (causing the weapon to start skinny and end fat, not a typical weapon design). The handle is nonexistent, it's basically just a big edgy pommel. I'm guessing you were going for an ottoman style dagger since you mentioned your heritage and it seems similar, but while they do seem to have short handles (at least in proportion to the blade) they definitely have a handle section that runs straight away from the blade and has a proper place to grip the weapon. I would suggest taking the "handle" you have now and shrinking it a bit and making it just a pommel, and use a longish cylinder between that and the blades guardy piece as a handle.
Hope I wasn't too harsh with my cnc, just trying to help you learn. You have a long way to go, but you are definitely decent for only modeling for 3 months (especially since you probably don't spend all day doing it lol). Good job on properly getting them ingame to test and play around with, not exactly the easiest thing to do with all the item.dat editing and proper naming etc...
