Disguise self at will is very flexible.

I draw on bristol board, ink with pigment liners, then colour with coloursoft acrylic pencils. Here's a photograph of the specific tools I use:

I then scan into a computer and clean up any debris or minor errors.

If you're able to do it in a way that's actually enjoyable for the rest of the group, go for it. The problem with this sort of preference, however, is that a lot of people I've met and gamed with who set out with the specific intention of being "the weird one" end up just acting like annoying idiots. The ones who are good at it usually don't try to be weird on purpose, at least not as a primary defining feature of their character. They just play something fun and it works out however it does. Contrary to the popularity of the Slappy meme, most people don't enjoy playing with someone who thinks they're an actual clown, especially if they're bad at it. And if you must try to accomplish weirdness on purpose, do it in little bits, like the example in this comic. Be subtle and leave the polka dot costume, rainbow wig, and airhorn out of it.
