I guess it would depend on how much you would charge for the commission of those directional sets. “top down enemy stuff”? I’m uncertain of what that is exactly.
In the case for dragons it would be $100. They would be in only 4 directional (8 only if i can figure out a easy way) as they would be very complex in 8. I would likely be doing 4 direction for a lot of the larger enemies. It's a lot in comparison to just waiting for the packs but I would at least try and give anyone who would commission something like this exclusive versions alongside whatever is made for the store. Hope that clears it up some.
