just editing is totally okay... what you doing in your pc is your business... but if you want to publish or release it, pease publish it as add-ons, no need to reupload the whole part of the mod... that will make confusion...
Indra P! Let me start by saying that I'm a fan of your work, I bookmarked your blog with your original creations, all the stuff you do is fantastic. This mod right here, is one of my favorite for San Andreas and the quality in it is evident but there's just one big problem with it for me and that is: we are unable to change Claude's weight or muscles to visibly reflect his stats as we can with regular CJ.
Would you please consider coming back to this mod and releasing an updated version where that IS possible? I'd like to see Claude fat or muscular and it would give the full roleplay experience. I suspect the trouble you had with that, and the reason you opted not to include those features is because you would have had to edit all of the head models to include thicker necks/fat features when the bodies are changed.
I realize that might be time consuming, but Indra I think you owe it to this otherwise fantastic mod to buckle down and just do it, make this mod complete.
