Take OG LOC, his chain around his neck looks like its part of his skin. The peds are dated, pixelated and flat-not looking 3D. I was 1st out on the PS2 in 2004 and then a few years later on the PC & Xbox in 2005 and then Xbox 360 & mac three years later in 2008.
Its not necessarily your fault, its the fact that these are from a game that's rather old. but these SA peds are well quiet frankly LOW quality. I applaud your desire to get new Peds into the game, and I'm not trying to discourage you & wont vote so it doesn't show as only a 1 star.
