Be part of a group is a good option to improve the work and learn new techniques, as much as receive quality feedback from people that have the same interests than you.
In 2018 I participate in a Whatsapp group that proposed several themes to do studies, simple sketches or finished artwork, every day of the week.
Thanks to all "Ilustres" group for keeping me sharp.
Here are some of the art I did in 2018. Hope you enjoy!
