My suggestion:
If you are going for a Zelda-esc feel and control scheme, you need to work on the attack animations you provided. They are great by RPG standards,but they lack "extension" to work in a Zelda style game.
What I am saying by "extension" is that the weapons need to extend an entire body length at minimum during an attack. Your dual wielding person doesn't extend at all. The weapons need to be extended for gameplay purposes. It shows the player exactly where the collision boxes will be for the weapons.
Since the one guy is using daggers, I would make the extension just 16 pixels, 8 would be REALLY punishing to the player, especially in an online environment where lag is a factor. Swords/Axes would be upto 24.
Not only do the weapons extend, but the player extend his arm/s forward along with his body. Play Minish Cap or Link to the Past and just repeatedly slash your sword. Link isn't stationary. He lunges forward a bit with each swing. You need to add that into your sprite work if you are going for a Zelda style combat system.
Last, you could use more frames, at least for main weapons. Most every Zelda game has sword animations that show full swings in an 180 degree arc. GB did not, but did well with 90 degree arcs given the limitations of the technology. Just something to keep in mind.
I really like your tileset. It feels more Pokemon that Zelda to me, though. It feels very 16x16 for an RPG instead of more free flowing like a Zelda game would be. Try working on some 45 degree angle tiles? If you are going for a more Minish Cap style(which hardly used 45 degrees), then add more "natural" looking edges on the tiles.
Other than that, looks like a nice project. I would suggest Game Maker Studio(or GM8/8.1) as a much easier tool for Rapid Application Development. You can literally copy/paste a sprite, set it as an object's image, place it in the room and then run the game to see how it looks.
For a real gameplay experience, you could look into HTML5 with Javascript on Canvas to make a multi-OS compatible system. You have to keep in mind with making ORPG: if you want MMO, you HAVE to program a server side program. If you are just making simple 2-4 player, you do not, however, if you want to discourage hackers, you need a server side program to check and store a player's character instead of storing it on a local machine where they can edit it.
