If I can say my opinion, the first one is great, a good artist could add something to it, but it already looks very nice. I haven't any self-drawn tattoo, I think it must feel great to have one. I tried many times, but I really suck at drawing.
The second one is really hard to see, but at least the subject is sweet. It's a rabbit, isn't it?

But let me say something about your third tattoo: that's absolutely fantastic! I love everything about it - the color, the subject, the style.
if it is possible to understand something about a person from his tattoos, I would say you are quite a brilliant person, unpredictable, never banal.
great tattoos, love them
