I think you’re overthinking it! This community is for anyone and everyone who is looking to improve their skills, learn about the business side of things and just be part of a larger group of like-minded individuals in general. There might be certain styles of work that tend to do better in the critique arena due to SVS being based loosely around children’s book illustrations but I think you could still enter and do well. And even if you didn’t do well or even enter at all, there is still plenty to gain from just being a part of the SVS family.
I think your work is awesome and it doesn’t look out of place at all. Stick around a while, get comfortable and join the family:)
