Question A little income off platforms like Patreon - curious re: tax?

[Peachfield]

Hi! I do general anime-related drawings on both free and paid platforms and was curious, am I liable to pay any income tax for the money I make for doing this? I work part time and am in full time education, does this make any difference to taxes? I'm in the UK if it helps. I've had a look at a tax calculator I found online but it's not been too helpful figuring this out - does anyone have any ideas? Thanks!
