Help understanding my recent transactions and why tx fees were so high

Hello, I'm having trouble understanding where my ethereum went and why transaction fees were so high. Basically I'm trying to figure out if I screwed something up. Here's the blockchain info for my wallet. https://etherscan.io/address/0xF12A63Ed8Ae6160FA8dD459d1b974dD0Eb47eAd4

I have a deposit of around 0.1 ethereum; and then two outgoing transactions of 0 ether, but big tx fees. Its a metamask account that I was using to mint some artwork on rarible.

Confused. I don't do much with Ethereum, and I'm wondering if I set the transaction incorrectly or what. Thanks.
