Hey thanks so much for creating this class! It's been super helpful so far and I'm looking forward to practicing more in the next few days.
Here's my pinterest board with some inspiration: https://www.pinterest.com/reuler/enamel-pins/
I tend to like the really bright colors, either a mix of limited tones or variations of the same color (like the leaf) as well as pins that almost have a stained glass effect, I think that the metal linework reminds me of leading.
I'm going to go with a gems theme - here are the sketches:
And here's the first version - I wanted to retain an imperfect/hand-drawn effect, although I do like how neat vectors can get.
I'll try to post some of my other trials in the next couple days. Thanks again for a great class!
