I don't think any of them are really bad, and I love mine lol. But you promised that they weren't gonna be anything spectacular, and they're free (like you mentioned)! I saw "five second" art and I actually expected something hilariously scary, even though I thought my request was pretty simple, and although you spent longer than 5 seconds on my octopus, you still spent very little time on it and I still think it's very nice. I'm sure that the art you actually put some time and love into is fantastic.
Actually no it's all crap xD I suck at drawing on technology but my paper pencil roses and eyes are killer.
