i saw a post asking about how to not make heavy, soldier and engie sameface and it annoyed me so here. i may not be most qualified for this but I think if you spend time looking at the characters enough you can easily find differences.

the most important thing is to keep in mind the overall face shape as well as the spacing between the features. if you are having trouble and find they look the same then go look at pictures of em for awhile and draw from them and it should really help.
