It's not too bad.
I'd be interested in an Aerial view of the map.
Since you're going for a Deathmatch, you want to consider a few things.
You're having a few flintlock guns and muskets.
Swords, bows, spears and axes.
So, you want each side to have a few things to accomodate this people.
A couple of lookout towers on either base makes sense, and can house an archer.
You want a couple of battlefields where sword fighting can take place.
But, it has to be an area where it's not so easy to just shoot everyone.
A tight area, surrounded by some high hills prevents gunmen standing at the sides and shooting inwards.
It also means that people in the centre with guns, are going to have a hard-time against swords men jumping around them.
You've got horse back troops fighting.
So, you want them to be able to have an area in which they can fight each other.
You want atleast one large open area for cavalry to run down people and for troops to shoot each other or fight with swords.
You don't want to keep the troops in one area.
You don't want everyone fighting in one place, and you don't want everyone spawning in their bases.
Set up some spawns around the map.
This way, people can't be trapped in their base.
Think about how you would want the game to play.
And how you would imagine you can give everyone a chance.
And build, while thinking of these.
I like your build so far, but if it's a Deathmatch you're building, you just need to make sure that it's fair for everyone and enjoyable.
But, well done so far.
