Crimson Daggers — Art forum

Hiya guys! I'm designing a character for a personal illustration and I'd like some feedback on these thumbnails. They're still very rough, I mostly concerned myself with the overall silhouette of the character, but before I start refining I'd appreciate any input you guys have at this point. Feel free to point out anything that feels wrong and let me know which ones you think are the best and worthy of being refined. Thanks a lot!

Those all look nice but 3 and 5 stand out to me the most.
