Thanks for all your advice, everyone! I wanted to give a little update because this week has been going well in this sense. The spread I'm working on for my client this sprint is one that I'm actually very happy with and excited about, so it's been a lot easier to get motivation for that. Plus, yesterday I just did a little 2 hour study just for fun of my cat, and I just completely lost myself in it. I was experimenting with new procreate brushes and high contrast lighting from a good reference. It turned out really nice. I think just doing realism studies can help me get in the zone and not think too much about what I'm doing. And I'm sure the practice is good too!
Hopefully I can keep this kind of energy up, because I've actually been feeling very good about drawing after reading all your lovely comments ❤
