Free Advice that don't cost $5, it's very rude to go around commenting and messaging people to ask them to commission you. It's annoying cause no one wants junk messages and solicitations for things they didn't ask for, which will end up with you just getting blocked and/or turned down.

Your art looks like it has potential, but all you're going to do is turn away clients by pestering them like this. And random people like myself will see this comment and likely just block you before you even know we exist, further harming your potential to get sales later on.
