[WIP] Starting town for my D&D campaign need help/criticism

[DarkInfinity]

OK, so I'm new at this and kinda just throwing myself to the wolves. Here is the setup, I've gotten my kids (ages 4 and 7) interested in playing D&D. I have a campaign idea started. It's a simple, not a lot of tricks (yet), you have been asked to deal with some goblins raiding local farms. (it's a little more exciting than that, if you want to see the rough draft of the campaign notes feel free to ask)

Part of the campaign when discussing the recent attacks there is reference to a map of the local area on the table. I'm trying to work on that map.

Basic layout, there is a walled city at the base of a mountain range between those mountains and a river.
It's not quite a large enough city to warrant having a castle, so the Earl resides in what I am calling a manor house
There are several farms surrounding the city. (these are important to the map because the map is eventually going to show where the attacks have happened.)
There is a road from the city to the river where there is a bridge crossing said river.
Out side of the farming region there are forests (being around the foothills of this mountainous range, I was thinking evergreens, but I could be talked into deciduous.)

Other notes:
There is mention of markers on the map for where a war is drawing closer to the city (not yet shown on this WIP Map)


My own critiques and questions:

• Clearly scale is off here. Should I just put a marker for the city and not add the detail therein?
• Again with Scale should the river be more of a line than having too much width? And a marker for the bridge?
• I would love some suggestions on what to do to show trees... I tried but it's becoming a mess...
• Farms? What's a good way to show farms?
• Maybe this should be in the Regional section I wasn't sure where this actually fit...

Feel free to tear me down, I'm a big boy, and I realize there are issues with this map. It's a first draft, the more I know what to fix, the better the next draft will be.

Thank you for any advice.
