What is a Chevron?

Basically I have been listening to a lot of chillwave/glofi music recently (in particular Washed Out's newest album 'Within and Without'. I am really trying to get into the genre as an artist and have so much passion for the sound. 

The only problem is I seem to be doubting whether I am getting anywhere close to a good sound. I am currently listening to Toro Y Moi, Washed out, caribou, bonobo, com truise, neon indian, gold panda and Tycho.

heres a sample of some stuff I came up with just to practice my production techniques. I just want good, honest opinions about the sound and melodies.
