2 Xmas presents - flopped flushes - line check

Presents from Santa. Did I screw up at any point.

As background, I'm taking a shot at $1BB poker. I have been doing well at $0.50BB. I'm playing kind of short stacked to get used to it. Comments on any streets would be welcome. I'll post results later.

Hand 1 no reads. This is my 4th hand at the table. Was I too passive? Maybe scared of all those funny colored chips?

Hand 1

hero $47.50
MP1 has me covered

SB posts small blind $0.50.
BB posts big blind $1.00.

Hand 2. This villain is somewhat maniacal (65/17/2.4 over 52 hands). 3 hands previously, he called me all the way down to the river with middle pair, where he made two pair and checked behind.

Villain has me covered
