For the curved Rectangles in Photoshop just click and hold on the rectangle/circle etc tool (under the Text and Path selection tool)
It will come up a list at the side, click on curved rectangle tool, pick your colour and draw your rectangle
To add the stroke click on 'Layer' then 'Layer style' and click on 'stroke' from there you can change the colour and width of the stroke, easy!
Also the little villager sprites look nicer if you leave them at their current size, to use the sprites open them up in Photoshop and click on 'Image' then 'Mode' and change it to 'RGB'. This will then allow you to drag and drop the sprite onto your other image using the 'move tool'
Hope this helps everyone to make their own custom designs ^^
If anyone needs any more assistance with creating signatures on Photoshop pop me a message and I should be able to help

Also be sure to save your image as 'PNG' if you want it to be transparent ^^
(Save a copy of the PSD file for easy editing when you need to add/remove villagers etc
)
