Help Required with Minimap

Hey everyone!

So first off, I’m trying to create a minimap, I currently have it so it has a render target 2d that is in the world and tracks the player as it moves around in the X and Y coordinates, the render target updates the texture and that is then put into a widget so the player can see where they are; the cursor in the middle is just an image that rotates depending on what the rotation of the player is. So that much is done, and it looks fairly good.

So my question is how can I add waypoints or little images on the minimap (like locations, blacksmith, etc.) without killing performance too much, and they would only stay in that spot (blacksmith doesn’t move, it just stays in that location in the level).

Here’s what it looks like so far:
