They are really bad, sorry. You've used the standard Paint colours, wich are poison. What's even worse, are that you didn't save them as PNG but als JPG! That is even deadly. Also, you only have given three trainers some new colours, and the second one a new head. I know that you are new, so you'd best read some tutorials. I also give as advice that you should better start with pokemon, not trainers. Their colour palette is not as good.
