I would love to get feedback on the cc hair I made

Hi. You should always start by studing a similar maxis item
1). delete the geometry that covers the hole in the hairline, it does not align with the scalp;
2). There is loose geometry in the scene. If the process of modelling included deleting or extruding anything, it is best to end it by selecting everything with A and Mesh - Clean up - Delete loose;
3). There should be two uv maps: uv_0 and uv_1. The first one projects the textures, the second one is responsible for morphing. In your case, there is one uv map with the wrong name that projects textures of the hair and two uv maps for the hairline only;
- rename the hairline to Hairline;
- select top, in 3d view press Shift D, then Esc to duplicate. Do the same with head_2. Select top.001, Shift-select head_2.001, press Ctrl J to join, rename to Reference;
- select the hair again, delete both uv_0 and uv_1, rename UVmap to uv_0, create uv_1;
- select the hairline, delete uv_0, rename UVmap to uv_0;
- shift-select the hair, join;
- delete Reference.
4). The hair should always be rigged manually, not through weight transfer. The neck bone should not affect the tail and the transition between bones should be smoother
5). This hair must be vertex painted with 3 colors
6). It would be best to unwrap the uvs in uv_0 the maxis way but i'll leave them as they are
7). do not unparent feet, do not do anything to body parts under the rig, the game may not like that
Here are an edited blend and package files
