It's great that you have ported sounds, sprites and gfx along with the view models. But in case of gfx and sprites, you have not renamed them as you have done for the view models so they don't work simply by extracting the zip. People who download this pack will have to configure the sprites and rename the gfx files manually.
The package is also missing PeeWees for all models which are always appreciated as they add to the enjoyment.
Another thing that spoils enjoyment is that even though this is a pack containing skins of a similar theme, all the weapons don't contain the same arms - skins have the male, female, hq and long arms - 4 different ones in the same package that kind of spoils the theme. Also ones that have the male hands don't have a female counterpart version available and vice versa. I don't know if this is a problem with the original CSO skins themselves or a consequence of porting but the arms skin textures are also not seamless, there are black cuts visible in them which are absolutely noticeable in-game, probably due to UV mesh slip-ups.
For plus points, excepting a few skins like Deagle, MP5, AK47, the others have cool animations that are a treat to watch. The sounds are good and match the anims. The CSO gold color schemes are also great, except that it looks odd/unrealistic to have a gold colored scope as well.
