I am modeling a character for someone and i plan on using a front and side view reference while modeling the character, first i am going to model the head then the body afterwards and i wanted to know before i start if there are any techniques or tips when doing models such as these. like should i start with certain shapes or a certain amount of polygons? and how do i fix triangles and are triangles as bad as people say they are and ect…? any advice would be greatly appreciated 
Wish you the best on your upcoming project! Might I suggest to first go and watch a couple tutorials on modeling a character and to follow along with them. This way by doing them, you will get the skillset and know how to be able to better model your own project. Hope that helps

He has some other characters that he’s done also that are great.
thank you very much for such helpful advice
