Welcome aboard Polliwog. I agree with Amok, simple works. Don't get me wrong there are some incredible complex pieces but those are usually done by incredible artists. Simple tends to read well from a distance.
Graeme is spot on, let everything settle down before you stress out over it. My first one bled ink a lot but turned out fine, and my second set didn't bleed much ink at all. There are a million factors that could play into it as well. Diet, hydration, location, ink color, technique, etc.
Keep in mind getting a tattoo is injuring the skin so some bruising and inflammation can happen.
Peace,
