is my iris (colored part of my eye) weird?!

ok, so i have, sort of lightish brown eyes. i have noticed on my iris, the colored part of my eye, that like... im not sure how to explain it. the like, design is weird. like almost everyone i know has like little lines or flecks of different shades in their eye. like you can only tell when you look super close. but i have noticed mine aren't like that. they have these little. "spots" i guess you could call them. like they are all different shapes and in like, a starish pattern. if i look up into the light they look like holes, like you can see the shadows. almost like little indents. or "tears". so yeah im a little worried, but they have always been that way. but i noticed while taking out my contacts and then looked at my moms eyes and then mine again and mine just look... different. is this normal? can you go look at you eyes an tell me if they are kind of even close to what i just said? or tell me how they look. i'm worried that i have like... holes or rips or something, but my eye doc. has never said any thing about it, so idk.
