Cosplay Advice!!

Im kind of new to cosplaying homestuck, and Im looking for any advice for making any sort of character cosplays :0

so far ive already made one troll and would like to do more, but the handmade horns I made for it are super finicky and Im worried about using the same method with bigger horns (ie Gamzee, Tavros, ect)

Id also love to do some of the kids as cosplays too, but Im unsure how to make myself recognizable if i kept the outfits simple, or where to even start if I were to attempt god tier outfits :U

please shoot out any tips & tricks you might have, anything is helpful!! :]
