Looks perfect for a medieval setting, though to push the limits I might add the option of a little flair piece at the hilt of the weapon (a ribbon or something to give it a little pop in color). Or maybe some paint decal along the shaft or the blade.
What you may find when making an entire set of these weapons is that everything will be brown and grey, which overall isn’t too appealing. When placed into a world full of dirt, stone, grass and typical fantasy settings, all the weapons will simply blend into the background, which is the opposite of what you’d want since the tip of the weapon is where all the action takes place.
The spear currently is good overall, I’m just thinking along the lines of further separating your pack from the competition in terms of it being the best possible option when deciding what to purchase.
I’d also mention that this is clearly a medieval weapon, and far from ancient. I’m guessing you know this already and are just showing WIP of the first asset but I’ll go ahead and say it just in case - when I think ancient I think primitive materials and processes - not forged steel and cured leather.
I’m not trying to cross promote in any way, but we do have some good references for primitive weapons (I’m biased of course) - Indigenous is Recruiting! - Job Offerings - Epic Developer Community Forums! It may be helpful in some way, I dunno.
