Suggestion, it would be nice if the preview image on posts was larger, and allowed different aspect ratios. I imagine maybe the current limit has to with bandwidth and delivery speed. Since all preview thumbnail images are both small, and cropped to a landscape format, viewer interest is largely dependent on what they can see appearing inside that window.
I created this digital painting (Sketchbook app on Surface Pro) for the #foodpaintchallenge on Instagram. This week's theme is gummi bears (see @alaiganuza or @dennispfeil.art for the source image). I wanted the most intense color possible while still remaining pleasing to the eye. Do you think it works or is it too much?
