Hey there @tricey, welcome to the Community Forum!
As we are continuously training and developing our models, we’d really appreciate if you could forward your original image to us so that we can improve our current Background Removal tool. Feel free to send this to me via DM or support@vectornator.io
Regarding the remaining sections, I recommend checking out the answer provided in this thread as to how to use Masking to remove targeted parts of your image. It is not possible to enable transparency in an active artboard, however, while exporting to PNG or SVG you will be offered the option to ‘Include Background’ which, if unchecked, will result in a transparent background.
Cheers,
Helen
