The faces on most of them, probably from earlier on in their artistic "career," look a lot like Tite Kubo's work/Bleach. Reminds me a lot of (NitroTitan/ModeSeven/whatever they're calling themselves these days) in their earlier days around the late 00s to really-early 10s. I bet quite a few artists with a manga/anime-inspired style who were trying to advance their skills or become more distinctive ended up influenced by Kubo, as his art was a fair bit different from most other series at the time, and it was at the height of its popularity in both the west and Japan.
