I already have a topic set up on SF, but what I have might help here as well.
Here are some map sprites I put together.
First off, the female Fighter and Warrior. I'm sure these are fairly common among GBA FE sprite topics, but I wanted to try my hand at it. I stuck with the hair bun because I liked that style the best for these sprites.
The Merchant, however, is a more original endeavor. It's the result of a concept of making a self-defense-viable version of the Transporter, obviously based on FE13!Anna as a model. That's why I used the female Myrmidon's head.
If you would like more details or want to offer critiques or suggestions, feel free.
